In versions prior to 2026.7, the REST API did not properly enforce the scope of project- and workspace-scoped teams, allowing a user to submit invalid team configurations through the API. By assigning projects to a team via these unvalidated requests, a user could grant access to projects they were not authorized to see or manage. This could expose private projects and permit translation, repository, and project-management operations outside the user's intended permission scope. This issue is fixed in version 2026.7.","cvss_v4":null,"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-639"],"references":["https://github.com/WeblateOrg/weblate/commit/19babc99b05f2cc299b5090f90f79d8181f25d79","https://github.com/WeblateOrg/weblate/security/advisories/GHSA-2q2q-jr9g-v9rf"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:17.453294893+00:00"},"epss":{"cve":"CVE-2026-55228","score":0.00448,"percentile":0.38966,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-2q2q-jr9g-v9rf","url":"https://osv.dev/vulnerability/GHSA-2q2q-jr9g-v9rf","summary":"Weblate has IDOR in GroupViewSet that allows authenticated project manager to gain unauthorized read access to any private project","modified":"2026-09-10T12:26:08.096875370Z","packages":[{"ecosystem":"PyPI","name":"weblate","purl":"pkg:pypi/weblate","ranges":["<2026.7"],"fixed":["2026.7"]}]},{"id":"PYSEC-2026-3942","url":"https://osv.dev/vulnerability/PYSEC-2026-3942","summary":"Weblate has IDOR in GroupViewSet that allows authenticated project manager to gain unauthorized read access to any private project","modified":"2026-09-10T12:15:14.167450674Z","packages":[{"ecosystem":"PyPI","name":"weblate","purl":"pkg:pypi/weblate","ranges":["<2026.7"],"fixed":["2026.7"]}]}],"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).
