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-2026-8829 in the wild and no public exploit code.\n\nAffected product: OALDERS HTML::Entities. 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-2026-8829/ (Markdown: https://insights.sbomify.com/CVE-2026-8829/index.md)","id":"CVE-2026-8829","markdown":"https://insights.sbomify.com/CVE-2026-8829/index.md","name":"CVE-2026-8829","record":{"aliases":["AZL-89451","BELL-CVE-2026-8829","DEBIAN-CVE-2026-8829","ECHO-a119-605d-66fd","GHSA-9p7j-9995-m88w","MGASA-2026-0264","OESA-2026-2672","SUSE-SU-2026:22189-1","SUSE-SU-2026:2948-1","SUSE-SU-2026:2950-1","UBUNTU-CVE-2026-8829","USN-8587-1","openSUSE-SU-2026:10957-1","openSUSE-SU-2026:21126-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl HTML::Entities library","requires_auth":"none","summary":"An attacker can trigger a use-after-free in HTML::Entities to disclose adjacent heap memory contents via crafted entity references.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[{"product":"html\\","vendor":"oalders"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"HTML::Entities versions before 3.84 for Perl read freed heap memory in _decode_entities.\n\nThe XS routine backing HTML::Entities::_decode_entities cached a pointer (repl) into the entity-value SV returned by hv_fetch on the entity2char hash.
