CVE-2026-62925: Gitea Alpine package parsing memory exhaustion

• Severity: medium (CVSS 6.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-10-14 · updated 2026-10-14
• Weakness: CWE-400

Description

Gitea parses Alpine package uploads before enforcing package-size quotas and does not bound the decompressed .PKGINFO data or its dependency and provides entry counts. An authenticated user with package-publish permission can upload a small, highly compressed archive that causes disproportionately large memory allocations during parsing and metadata generation. On memory-constrained deployments, this can terminate the process or otherwise disrupt availability.
