In versions prior to 5.17, repository-boundary validation relies on string prefix checks on resolved absolute paths. In multiple code paths, the check uses startswith against the repository root path. This is not path-segment aware and can be bypassed when the external path shares the same string prefix as the repository path (for example, repo and repo_outside). This issue has been fixed in version 5.17.","published_at":"2026-04-15T18:36:44.975000Z","last_modified_at":null,"cvss_v3_score":5.0,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","cvss_v3_severity":"MEDIUM","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-22"],"nvd_references":["https://github.com/WeblateOrg/weblate/security/advisories/GHSA-ffgh-3jrf-8wvh","https://github.com/WeblateOrg/weblate/commit/e30dbcb33ae78e754ecef192d54f996b89cb4e15"],"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":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:11.113779Z"},"effective_severity":"MEDIUM","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":"C","value_label":"Changed"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"weblateorg","vendor_name":"WeblateOrg","product_slug":"weblate","product_name":"weblate","version_start":"< 5.17","version_start_inclusive":true,"version_end":"< 5.17","version_end_inclusive":true,"cpe23_uri":"cve5:weblateorg:weblate:< 5.17:< 5.17"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/WeblateOrg/weblate/security/advisories/GHSA-ffgh-3jrf-8wvh","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/WeblateOrg/weblate/commit/e30dbcb33ae78e754ecef192d54f996b89cb4e15","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-04-15T18:36:44.975000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:53:49.239492Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:49.239492Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:49.239492Z","label":"CVSS score revised","source":"cvelistv5"}]}
