Archived Security Brief

Sunday's disclosures center on widely deployed infrastructure and developer tooling, including Palo Alto Networks PAN-OS, the LiteSpeed cPanel plugin, and GitHub Actions OIDC, all carrying CVSS 9.5 ratings. The brief covers 1 critical CVE (down 94% from 18 the prior day) and 30 high-priority CVEs (down 52% from 63), reflecting a much lighter critical workload than Saturday. The lone critical entry is CVE-2018-25412 (CVSS 9.8) in Delta Sql, while CVE-2026-0257 in Palo Alto PAN-OS and CVE-2026-45321 in GitHub Actions OIDC stand out among the high-severity set. Affected components span network security appliances, hosting control panels, and CI/CD identity flows, increasing exposure for organizations running internet-facing management interfaces and automated build pipelines. No patches are currently reflected for these entries, so teams should prioritize compensating controls and monitor vendor advisories for fix availability.

  • Palo Alto Networks PAN-OS (CVE-2026-0257, CVSS 9.5) leads the day's high-impact set affecting internet-facing network security appliances
  • Critical CVEs fell to 1, a 94% decrease from 18 the prior day
  • High-priority CVEs totaled 30, a 52% decrease from 63 the prior day
  • Developer and hosting infrastructure is heavily represented, including LiteSpeed cPanel Plugin (CVE-2026-48172) and GitHub Actions OIDC (CVE-2026-45321)
  • Patch availability stands at 0%, requiring reliance on configuration hardening and access restrictions until fixes ship
