It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-8612 in the wild and no public exploit code.\n\nAffected product: OALDERS WWW::Mechanize::Cached. 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-2026-8612/ (Markdown: https://insights.sbomify.com/CVE-2026-8612/index.md)","id":"CVE-2026-8612","markdown":"https://insights.sbomify.com/CVE-2026-8612/index.md","name":"CVE-2026-8612","record":{"aliases":["GHSA-38r9-g25v-vcvr","MGASA-2026-0149"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Perl HTTP caching library","requires_auth":"low_privilege","summary":"A local attacker can forge cached HTTP responses in a world-writable directory, leading to arbitrary code execution via unsafe deserialization in Perl applications.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[{"product":"www\\","vendor":"oalders"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"},{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"WWW::Mechanize::Cached versions before 2.00 for Perl deserialize cached HTTP responses from a world-writable on-disk cache, enabling local response forgery and code execution.\n\nWith no explicit cache backend, WWW::Mechanize::Cached constructs a default Cache::FileCache under /tmp/FileCache without overriding the backend's documented directory_umask of 000, so the cache root and its subdirectories are created mode 0777 with no sticky bit. Cache entries are named by sha1_hex of the request and read back through Storable::thaw on the next cache hit.\n\nA local attacker with write access to the cache tree can replace a victim's cache entry for a known URL with an arbitrary frozen HTTP::Response blob, causing the victim's next get() of that URL to return attacker controlled response bytes. Because the bytes are passed to Storable::thaw, a victim process that has loaded any class with a side-effectful STORABLE_thaw, DESTROY, or overload hook can be escalated to arbitrary code execution.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Deserialization in WWW::Mechanize::Cached","id":"CVE-2026-8612","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in aThemes Addons for Elementor","id":"CVE-2026-8613"},"packages":[],"prev":{"headline":"Information disclosure in Klamra Paycal for Aspaclaria","id":"CVE-2026-8611"},"products":["WWW::Mechanize::Cached"],"published":"2026-05-15","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-15","vendors":["OALDERS"]},"summary":"A local attacker can forge cached HTTP responses in a world-writable directory, leading to arbitrary code execution via unsafe deserialization in Perl applications.","url":"https://insights.sbomify.com/CVE-2026-8612/"}
