It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-32825 in the wild and no public exploit code.\n\nAffected product: bblfshd. 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-2021-32825/ (Markdown: https://insights.sbomify.com/CVE-2021-32825/index.md)","id":"CVE-2021-32825","markdown":"https://insights.sbomify.com/CVE-2021-32825/index.md","name":"CVE-2021-32825","record":{"aliases":["GHSA-63p8-63ff-xr65"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Source code parsing server","requires_auth":"none","summary":"Attackers can exploit unsafe symlink handling in archive unpacking to read or write arbitrary files outside the target directory.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"bblfshd","vendor":"bblfshd_project"}],"cvss":{"score":2.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"},{"id":"CWE-23","name":"Relative Path Traversal"}],"description":"bblfshd is an open source self-hosted server for source code parsing. In bblfshd before commit 4265465b9b6fb5663c30ee43806126012066aad4 there is a \"zipslip\" vulnerability. The unsafe handling of symbolic links in an unpacking routine may enable attackers to read and/or write to arbitrary locations outside the designated target folder. This issue may lead to arbitrary file write (with same permissions as the program running the unpack operation) if the attacker can control the archive file. Additionally, if the attacker has read access to the unpacked files, he may be able to read arbitrary system files the parent process has permissions to read.
