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.","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","score":5.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-20","CWE-918"],"references":["https://github.com/WeblateOrg/weblate/commit/e1eff1f517c1ee315d69581910baaabb724e5ef0","https://github.com/WeblateOrg/weblate/commit/e4b67a76d95d5165ecb9937f7485fd79223b7f14","https://github.com/WeblateOrg/weblate/pull/19061","https://github.com/WeblateOrg/weblate/pull/19062","https://github.com/WeblateOrg/weblate/releases/tag/weblate-5.17.1"],"products":["weblate:weblate"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-41654","score":0.00371,"percentile":0.30808,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-cwcx-382v-8m9g","url":"https://osv.dev/vulnerability/GHSA-cwcx-382v-8m9g","summary":"Weblate Vulnerable to Authenticated SSRF via Project Backup Import bypassing validate_repo_url","modified":"2026-07-13T07:26:39.185031697Z","packages":[{"ecosystem":"PyPI","name":"weblate","purl":"pkg:pypi/weblate","ranges":["<5.17.1"],"fixed":["5.17.1"]}]},{"id":"PYSEC-2026-2317","url":"https://osv.dev/vulnerability/PYSEC-2026-2317","summary":"","modified":"2026-07-13T07:15:48.299381512Z","packages":[{"ecosystem":"PyPI","name":"weblate","purl":"pkg:pypi/weblate","ranges":["<5.17.1"],"fixed":["5.17.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
