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-2026-8454 in the wild and no public exploit code.\n\nAffected product: TONYC Imager::File::GIF. 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-2026-8454/ (Markdown: https://insights.sbomify.com/CVE-2026-8454/index.md)","id":"CVE-2026-8454","markdown":"https://insights.sbomify.com/CVE-2026-8454/index.md","name":"CVE-2026-8454","record":{"aliases":["GHSA-8r2w-8p2v-h4g4"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Perl GIF library","requires_auth":"none","summary":"Attackers can trigger heap out-of-bounds writes via crafted multi-frame GIF files, potentially leading to code execution or crashes in applications using this Perl library.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[{"product":"imager\\","vendor":"tonyc"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Imager::File::GIF versions through 1.002 for Perl allow a heap out of bounds (OOB) write on crafted multi-frame GIF files.\n\nImager::File::GIF's i_readgif_multi_low allocates a single per-row buffer GifRow sized for the GIF's global screen width 'SWidth' and reuses it across every image in the file.\n\nThe page-match branch validates Image.Width + Image.Left \u003e SWidth before each DGifGetLine write, but the parallel skip-image branch at imgif.c:790-805 calls DGifGetLine(GifFile, GifRow, Width) with no such check.","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":"Memory corruption in Imager::File::GIF","id":"CVE-2026-8454","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"WooCommerce - Social Login \u003c= 2.8.7 - Unauthenticated Authentication Bypass via Forged Apple 'id_token' JWT","id":"CVE-2026-8457"},"packages":[],"prev":{"headline":"** REJECT ** DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2026-8453"},"products":["Imager::File::GIF"],"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":["TONYC"]},"summary":"Attackers can trigger heap out-of-bounds writes via crafted multi-frame GIF files, potentially leading to code execution or crashes in applications using this Perl library.","url":"https://insights.sbomify.com/CVE-2026-8454/"}
