Alert meAnalysisAIv1 – Jul 06, 2026
Canonical URL spoofing in Gitea before 1.25.5 lets remote attackers inject malformed X-Forwarded-Proto values that the server trusts when computing its public-facing URL, causing it to emit attacker-controlled canonical links (e.g. in emails, redirects, and generated absolute URLs). No public exploit identified at time of analysis, and the low EPSS score (0.17%, 6th percentile) reflects minimal in-the-wild interest, but a vendor patch is available in v1.25.5. Note that the published CVSS vector claims availability impact (A:H) while the description describes URL spoofing (an integrity concern), a discrepancy worth verifying with the vendor.

Lifecycle Timeline
2DescriptionCVE.org
Gitea versions before 1.25.5 accept malformed or injected forwarded-proto values when detecting public URLs, allowing spoofed canonical URL generation.
Executive ViewAI
Gitea versions prior to 1.25.5 allow attackers to inject malicious URLs into system-generated emails and redirects, creating phishing and credential harvesting risks for development teams. A vendor patch is available and should be prioritized to eliminate this integrity exposure.
Within 24 hours: Identify all Gitea deployments and document version numbers to determine exposure scope. Within 7 days: Plan and test upgrade to Gitea v1.25.5 or later in a staging environment, verifying X-Forwarded-Proto header handling post-patch. Within 30 days: Deploy v1.25.5+ to production and confirm canonical URL generation is correct.
Apply vendor patch: upgrade Gitea to v1.25.5 or later.
