An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-33435 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- weblate (PyPI): affected all versions; fixed in 5.17\n- weblate (PyPI): affected all versions; fixed in 5.17\n- Weblate (PyPI): affected all versions; fixed in 5.17\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-33435/ (Markdown: https://insights.sbomify.com/CVE-2026-33435/index.md)","id":"CVE-2026-33435","markdown":"https://insights.sbomify.com/CVE-2026-33435/index.md","name":"CVE-2026-33435","record":{"aliases":["GHSA-558g-h753-6m33","PYSEC-2026-154"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Weblate localization tool","requires_auth":"high_privilege","summary":"Attackers can achieve remote code execution by uploading malicious Git or Mercurial configuration files during project backup restoration in Weblate.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"weblate","vendor":"weblate"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"},{"id":"CWE-23","name":"Relative Path Traversal"}],"description":"Weblate is a web based localization tool.
