An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-82035 in the wild and no public exploit code.\n\nAffected product: PyMuPDF. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-82035/ (Markdown: https://insights.sbomify.com/CVE-2026-82035/index.md)","id":"CVE-2026-82035","markdown":"https://insights.sbomify.com/CVE-2026-82035/index.md","name":"CVE-2026-82035","record":{"aliases":["DEBIAN-CVE-2026-82035","GHSA-434w-92hw-f2m3","UBUNTU-CVE-2026-82035","openSUSE-SU-2026:11824-1","openSUSE-SU-2026:21912-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"PyMuPDF library","requires_auth":"none","summary":"Attackers can write arbitrary files outside the intended directory by supplying a crafted document with malicious font names to PyMuPDF.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"PyMuPDF through 1.28.2, fixed in commit b2c8f3a, contains a path traversal vulnerability in the font branch of extract_objects() in src/__main__.py, where the output filename is constructed by joining a document-controlled BaseFont name directly onto the user-supplied output directory without stripping path separators or dot-dot sequences.
