Executive Summary:
A critical vulnerability has been identified in Firefox for iOS which allows a nearby attacker to intercept and hijack passkey authentication processes. By tricking a user into visiting a malicious webpage, an attacker within Bluetooth range can gain unauthorized access to the user's accounts, leading to potential account takeover, data breaches, and compromise of sensitive corporate systems.

Vulnerability Details

CVE-ID: CVE-2025-55031

Affected Software: Mozilla Firefox for iOS

Affected Versions: See vendor advisory for specific affected versions

Vulnerability: This vulnerability allows for a passkey authentication relay attack. An attacker can craft a malicious webpage that, when visited by a user on Firefox for iOS, uses a specially formed fido:// link to improperly interact with the operating system's passkey functionality. This triggers the hybrid passkey transport mechanism over Bluetooth Low Energy (BLE). An attacker within Bluetooth range can then present their own device to intercept the authentication request. The user, seeing a legitimate-looking prompt on their iPhone, may approve the sign-in, inadvertently granting the attacker access to their account on the attacker's machine. The core issue is Firefox for iOS's failure to properly validate the origin of the FIDO request before passing it to the OS for processing.

Business Impact

This vulnerability is rated as critical severity with a CVSS score of 9.8. Successful exploitation could lead to a complete compromise of user accounts that rely on passkey authentication, including access to corporate email, cloud platforms, financial systems, and other critical business applications. The direct business impact includes the high risk of data breaches, intellectual property theft, financial fraud, and significant reputational damage. As passkeys are adopted for privileged access, this vulnerability could also serve as an entry point for a wider network compromise.

Proactive Monitoring: Security teams should monitor for the following indicators of compromise:

• Unusual child processes spawning from EXCEL.EXE (e.g., cmd.exe, powershell.exe, wscript.exe).
• Outbound network connections from the EXCEL.EXE process to untrusted IP addresses or domains.
• Endpoint Detection and Response (EDR) alerts for memory corruption, process hollowing, or other suspicious behaviors originating from Microsoft Office applications.
• Creation of unexpected files, scheduled tasks, or registry modifications after a user opens an Excel document.

Compensating Controls: If immediate patching is not feasible, the following controls can help reduce the risk:

• Ensure Microsoft Office Protected View is enabled for documents originating from the internet or other untrusted locations. This feature opens files in a restricted, sandboxed mode.
• Implement user awareness training to warn against opening unsolicited email attachments, even if they appear to be from a known contact.
• Utilize application control solutions to prevent unauthorized executables from running on endpoints.
• Ensure antivirus and EDR signatures and behavioral detection rules are fully updated.

Executive Summary:
A critical vulnerability has been identified in the jwe Ruby library, a component used for encrypting data. This flaw allows an attacker to guess the authentication key for encrypted information, potentially leading to the complete decryption of sensitive data. Successful exploitation could result in a severe data breach, compromising confidential information protected by this library.

Vulnerability Details

CVE-ID: CVE-2025-54887

Affected Software: jwe is a Ruby implementation of the RFC Multiple Products

Affected Versions: 1.1.0 and below

Vulnerability: The vulnerability exists in the handling of JSON Web Encryption (JWE) authentication tags. An attacker can submit an encrypted JWE object with a guessed authentication tag to an application using the vulnerable library. By observing the application's response (e.g., a successful decryption versus an error), the attacker can systematically brute-force the correct authentication tag. Once the correct tag is discovered, the attacker can decrypt the JWE payload, leading to a total loss of confidentiality for the encrypted data.

Business Impact

This vulnerability is rated as critical severity with a CVSS score of 9.1. Exploitation could lead to the unauthorized decryption and exposure of highly sensitive data, such as Personally Identifiable Information (PII), financial records, API keys, or session tokens that are encapsulated within JWEs. The business risks include severe reputational damage, loss of customer trust, non-compliance with data protection regulations (e.g., GDPR, CCPA) leading to significant financial penalties, and the potential for further system compromise if authentication tokens are stolen.

Remediation Plan

Immediate Action:
Immediately identify all applications and systems using the vulnerable jwe library and upgrade to a patched version (above 1.1.0). Follow the vendor's guidance to ensure the update is applied correctly across all affected products and services.

Proactive Monitoring:
Implement enhanced monitoring on services that process JWE tokens. Specifically, monitor for and alert on a high volume of decryption failures originating from a single IP address or user, which could indicate a brute-force attempt. Review application and web server logs for patterns of repeated, slightly-varied requests to endpoints that handle JWEs.

Compensating Controls:
If immediate patching is not feasible, implement the following controls to mitigate risk:

• Use a Web Application Firewall (WAF) to implement strict rate-limiting on endpoints that process JWE tokens, making a brute-force attack impractical.
• Configure network and application firewalls to block IP addresses that exhibit suspicious, repetitive request patterns consistent with a brute-force attack.
• Isolate services using the vulnerable library from direct internet exposure where possible.

Exploitation Status

Public Exploit Available: false

Analyst Notes:
As of August 8, 2025, there are no known public proof-of-concept exploits or observed active exploitation in the wild for this vulnerability. The vulnerability is not currently listed on the CISA Known Exploited Vulnerabilities (KEV) catalog. However, the technical details provided in the disclosure are sufficient for a skilled attacker to develop an exploit.

Analyst Recommendation
Given the critical CVSS score of 9.1 and the direct risk of sensitive data exposure, it is strongly recommended that organizations prioritize patching this vulnerability immediately. All systems utilizing the jwe Ruby library version 1.1.0 or below should be considered at high risk. While there is no current evidence of active exploitation, the severity of the potential impact warrants urgent remediation to prevent future compromise.

Executive Summary:
A high-severity vulnerability has been identified in the skops Python library, which is used for sharing machine learning models. An attacker could exploit this vulnerability by creating a malicious model file. If this file is loaded by an application using the affected skops library, the attacker could execute arbitrary code and gain full control of the underlying system, leading to potential data theft, system compromise, and further network intrusion.

Vulnerability Details

CVE-ID: CVE-2025-54886

Affected Software: skops Multiple Products

Affected Versions: See vendor advisory for specific affected versions

Vulnerability: The vulnerability exists due to an insecure deserialization process when loading model files with the skops library. An attacker can craft a malicious model file containing embedded code payloads. When a vulnerable application uses the skops library to load this malicious file, the deserialization process improperly executes the embedded payload, resulting in arbitrary code execution with the permissions of the application running the skops library. Exploitation requires an attacker to convince a user or an automated system to load the specially crafted, malicious model file.

Business Impact

This vulnerability is rated as High severity with a CVSS score of 8.4. Successful exploitation could have a severe impact on the business, primarily through Remote Code Execution (RCE). An attacker could compromise critical systems used in MLOps pipelines, data science environments, or production applications. Potential consequences include theft of sensitive intellectual property (e.g., proprietary models, training data), unauthorized access to the organization's internal network, deployment of ransomware, or using the compromised system to launch further attacks. The risk is significant for any organization relying on the skops library to handle models from external or untrusted sources.

Remediation Plan

Immediate Action: Apply the security updates provided by the vendor to all systems using the skops library immediately. After patching, monitor systems for any signs of attempted exploitation. Review application and system access logs for any unusual activity related to model loading processes that occurred prior to the patch being applied.

Proactive Monitoring: Implement enhanced monitoring on systems running skops. Look for suspicious child processes being spawned by Python applications, especially shells (sh, bash, powershell.exe) or network utilities (curl, wget). Monitor for unexpected outbound network connections from servers that process models, as this could indicate a command-and-control channel. Configure logging to record all model loading events, including the source and hash of the file.

Compensating Controls: If immediate patching is not feasible, implement the following controls to mitigate risk:

• Restrict model loading processes to a sandboxed or containerized environment with minimal privileges and no outbound network access.
• Enforce a strict policy to only load models from trusted, internally-vetted, and signed sources.
• Use Endpoint Detection and Response (EDR) tools to detect and block anomalous process execution patterns on affected hosts.

Exploitation Status

Public Exploit Available: false

Analyst Notes: As of August 8, 2025, there are no known public exploits or active exploitation campaigns targeting this vulnerability. However, due to the high severity and the straightforward nature of insecure deserialization vulnerabilities, it is highly probable that proof-of-concept exploits will be developed and published by security researchers and threat actors in the near future.

Analyst Recommendation

Given the high-severity CVSS score and the risk of remote code execution, we strongly recommend that all affected systems are patched immediately. Organizations should prioritize identifying all instances of the skops library within their environment to ensure complete remediation. Although this CVE is not currently on the CISA KEV list, its critical nature makes it a prime candidate for future inclusion and an attractive target for attackers. Proactive patching and monitoring are essential to prevent potential compromise.
