An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-25779 exists.\n\nAffected packages and fixed versions:\n- github.com/go-gitea/gitea (Go): affected all versions; fixed in 1.26.0\n- github.com/go-gitea/gitea (Go): affected all versions; fixed in 1.26.0\n- code.gitea.io/gitea (Go): affected all versions; fixed in 1.26.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-25779/ (Markdown: https://insights.sbomify.com/CVE-2026-25779/index.md)","id":"CVE-2026-25779","markdown":"https://insights.sbomify.com/CVE-2026-25779/index.md","name":"CVE-2026-25779","record":{"aliases":["GHSA-j5r2-4c8j-xc3m","GO-2026-5448"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Git server","requires_auth":"none","summary":"Attackers can exploit backslash handling in redirect parameters to redirect users to malicious sites, requiring a patch to mitigate.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Gitea","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"Gitea versions up to and including 1.25.4 allow redirect bypasses through raw or percent-encoded backslashes in redirect_to values.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Gitea redirect handling permits open redirects through backslash paths","id":"CVE-2026-25779","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"open_redirect","year":"2026"},"n_packages":3,"n_references":5,"next":{"headline":"Memory Exhaustion via Malformed DOC File Upload","id":"CVE-2026-25780"},"packages":[{"ecosystem":"Go","fixed":["1.26.0"],"introduced":["0"],"last_affected":[],"package":"code.gitea.io/gitea","purl":"pkg:golang/code.gitea.io/gitea","source":"GO-2026-5448"},{"ecosystem":"Go","fixed":["1.26.0"],"introduced":["0"],"last_affected":[],"package":"github.com/go-gitea/gitea","purl":null,"source":"GHSA-j5r2-4c8j-xc3m"},{"ecosystem":"Go","fixed":["1.26.0"],"introduced":["0"],"last_affected":[],"package":"github.com/go-gitea/gitea","purl":"pkg:golang/github.com/go-gitea/gitea","source":"GHSA-j5r2-4c8j-xc3m"}],"prev":{"headline":"SWITCH EV swtchenergy.com Insufficient Session Expiration","id":"CVE-2026-25778"},"products":["Gitea Open Source Git Server"],"published":"2026-07-03","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-07","vendors":["Gitea"]},"summary":"Attackers can exploit backslash handling in redirect parameters to redirect users to malicious sites, requiring a patch to mitigate.","url":"https://insights.sbomify.com/CVE-2026-25779/"}
