Prior to 0.14.3, three API endpoints — PATCH /api/v1/repos/:owner/:repo/issue-tracker, PATCH /api/v1/repos/:owner/:repo/wiki, and POST /api/v1/repos/:owner/:repo/mirror-sync — are gated by reqRepoWriter() rather than reqRepoAdmin(). The equivalent operations in the web UI sit behind reqRepoAdmin, which requires AccessMode >= AccessModeAdmin. A write-level collaborator (who has AccessMode == AccessModeWrite < AccessModeAdmin) can therefore call these API endpoints directly to disable the native issue tracker or wiki, inject attacker-controlled external tracker/wiki URLs that redirect all repository visitors, or trigger mirror sync — none of which they are authorized to do. This vulnerability is fixed in 0.14.3.","published_at":"2026-06-24T20:27:41.410000Z","last_modified_at":null,"cvss_v3_score":7.1,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-863","CWE-269"],"nvd_references":["https://github.com/gogs/gogs/security/advisories/GHSA-268j-37xf-pp52","https://github.com/gogs/gogs/pull/8327","https://github.com/gogs/gogs/commit/6283462119bd8894f1599d70339b5e823f99954a","https://github.com/gogs/gogs/releases/tag/v0.14.3"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-28T17:55:22.518073Z","updated_at":"2026-06-28T23:30:49.088205Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"L","value_label":"Low"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"gogs","vendor_name":"gogs","product_slug":"gogs","product_name":"gogs","version_start":"< 0.14.3","version_start_inclusive":true,"version_end":"< 0.14.3","version_end_inclusive":true,"cpe23_uri":"cve5:gogs:gogs:< 0.14.3:< 0.14.3"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/gogs/gogs/security/advisories/GHSA-268j-37xf-pp52","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/gogs/gogs/pull/8327","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/gogs/gogs/commit/6283462119bd8894f1599d70339b5e823f99954a","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/gogs/gogs/releases/tag/v0.14.3","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-24T20:27:41.410000Z","label":"CVE published","source":null}]}
