An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-82481 in the wild and no public exploit code.\n\nAffected product: mirage cohttp. 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-2026-82481/ (Markdown: https://insights.sbomify.com/CVE-2026-82481/index.md)","id":"CVE-2026-82481","markdown":"https://insights.sbomify.com/CVE-2026-82481/index.md","name":"CVE-2026-82481","record":{"aliases":["DEBIAN-CVE-2026-82481","GHSA-qcjm-vmrx-v935","UBUNTU-CVE-2026-82481"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OCaml HTTP library","requires_auth":"none","summary":"An attacker can exploit a directory traversal vulnerability in the cohttp library to read arbitrary files from the server.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/AU:Y/R:A/V:D/RE:M","version":"4.0"},"cwes":[{"id":"CWE-180","name":"Incorrect Behavior Order: Validate Before Canonicalize"}],"description":"The cohttp package before 6.3.0 for OCaml allows directory traversal.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Path traversal in cohttp","id":"CVE-2026-82481","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"coppermine-gallery Coppermine Photo Gallery edit_profile Endpoint profile.php cross site scripting","id":"CVE-2026-82482"},"packages":[],"prev":{"headline":"NASA cFS cFE Software Bus cfe_sb_util.c CFE_SB_GetUserDataLength integer underflow","id":"CVE-2026-82480"},"products":["cohttp"],"published":"2026-08-29","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-01","vendors":["mirage"]},"summary":"An attacker can exploit a directory traversal vulnerability in the cohttp library to read arbitrary files from the server.","url":"https://insights.sbomify.com/CVE-2026-82481/"}
