Prior to version 5.17.1, an authenticated user with project.add permission (default on hosted Weblate SaaS and for any user holding an active billing/trial plan) can import a crafted project backup ZIP whose components/<name>.json contains an attacker-chosen repo URL pointing at a private address (e.g. http://127.0.0.1:9999/) or using a non-allow-listed scheme (e.g. file://, git://). Weblate persists the component via Component.objects.bulk_create([component])[0], which bypasses Django's full_clean() and therefore never runs the validate_repo_url validator. The URL is subsequently written verbatim into .git/config by configure_repo(pull=False). This issue has been patched in version 5.17.1.","published_at":"2026-05-07T13:40:12.532000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":5.3,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N","cvss_v4_severity":"MEDIUM","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-20","CWE-918"],"nvd_references":["https://github.com/WeblateOrg/weblate/security/advisories/GHSA-cwcx-382v-8m9g","https://github.com/WeblateOrg/weblate/pull/19061","https://github.com/WeblateOrg/weblate/pull/19062","https://github.com/WeblateOrg/weblate/commit/e1eff1f517c1ee315d69581910baaabb724e5ef0","https://github.com/WeblateOrg/weblate/commit/e4b67a76d95d5165ecb9937f7485fd79223b7f14","https://github.com/WeblateOrg/weblate/releases/tag/weblate-5.17.1"],"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":"2026-06-28T23:30:16.988718Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"L","value_label":"Low"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"N","value_label":"None"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"N","value_label":"None"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"L","value_label":"Low"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"weblateorg","vendor_name":"WeblateOrg","product_slug":"weblate","product_name":"weblate","version_start":"< 5.17.1","version_start_inclusive":true,"version_end":"< 5.17.1","version_end_inclusive":true,"cpe23_uri":"cve5:weblateorg:weblate:< 5.17.1:< 5.17.1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/WeblateOrg/weblate/security/advisories/GHSA-cwcx-382v-8m9g","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/WeblateOrg/weblate/pull/19061","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/WeblateOrg/weblate/pull/19062","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/WeblateOrg/weblate/commit/e1eff1f517c1ee315d69581910baaabb724e5ef0","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/WeblateOrg/weblate/commit/e4b67a76d95d5165ecb9937f7485fd79223b7f14","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/WeblateOrg/weblate/releases/tag/weblate-5.17.1","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-05-07T13:40:12.532000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:54:07.258310Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:54:07.258310Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:54:07.258310Z","label":"CVSS score revised","source":"cvelistv5"}]}
