Description
A heap-based out-of-bounds read vulnerability in RWObj_Reader::read in the OBJ file parser in Open CASCADE Technology (OCCT) V8_0_0_rc5 allows user-assisted attackers to cause a denial of service or obtain sensitive information by persuading a victim to open a crafted OBJ file
Remediation
Apply vendor security updates immediately. Monitor for exploitation attempts and review access logs.

VENDOR: MixPHP
PRODUCT: Framework
AFFECTED_VERSIONS: 2.x thru 2.2.17
---END_METADATA---
Description Summary:
The MixPHP Framework is vulnerable to unsafe deserialization of session and cache data stored on the filesystem, potentially allowing remote code execution.
Executive Summary:
An unsafe deserialization vulnerability in the MixPHP Framework allows attackers to execute arbitrary code by manipulating session or cache files on the server.
Vulnerability Details
CVE-ID: CVE-2026-42473
Affected Software: MixPHP Framework
Affected Versions: 2.x thru 2.2.17
Vulnerability: This is an unsafe deserialization vulnerability occurring in the
FileHandlerobject. The application performsunserialize()on data retrieved from the filesystem; if an attacker can write malicious serialized objects to these files, they can achieve remote code execution.Business Impact
Similar to other deserialization flaws, this vulnerability is rated 9.8 on the CVSS scale. It creates a significant risk of full system compromise, where an attacker can execute arbitrary commands, leading to data theft and unauthorized administrative access to the server.
Remediation Plan
Immediate Action: Update to the latest patched version of the MixPHP Framework and ensure all filesystem-based storage is restricted to trusted processes.
Proactive Monitoring: Monitor server logs and file integrity for unauthorized modifications to session or cache files.
Compensating Controls: Use file system permissions to ensure only the application service account can read or write to the specific session/cache directories.
Exploitation Status
Public Exploit Available: Unknown
Analyst Notes: As of May 1, 2026, there is no public information indicating active exploitation of this vulnerability. However, due to the nature of the flaw, the potential for exploitation is high.
Analyst Recommendation
Given the critical nature of deserialization vulnerabilities, immediate patching is required. Security teams should verify that the application environment is hardened against unauthorized file access to mitigate the risk until the update is deployed.
