Gitea · Gitea · CVE-2026-25779
**Name of the Vulnerable Software and Affected Versions**
Gitea (affected versions not specified)
**Description**
An open redirect exists due to improper validation within the `urlIsRelative()` function in `modules/httplib/url.go`. An attacker can bypass this validation by using directory traversal sequences combined with a back-slash in the `redirect to` parameter, allowing them to redirect users to an external domain. This can lead to phishing attacks, theft of OAuth or SSO tokens, leakage of sensitive information via the Referer header, and cache poisoning in environments using shared caches.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
