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-2026-8177 in the wild and no public exploit code.\n\nAffected product: SHLOMIF XML::LibXML. 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-2026-8177/ (Markdown: https://insights.sbomify.com/CVE-2026-8177/index.md)","id":"CVE-2026-8177","markdown":"https://insights.sbomify.com/CVE-2026-8177/index.md","name":"CVE-2026-8177","record":{"aliases":["ALSA-2026:39547","ALSA-2026:39553","ALSA-2026:39878","AZL-86550","CLSA-2026-1784553427","CLSA-2026-1784554254","DEBIAN-CVE-2026-8177","ECHO-d531-9d26-ac4f","GHSA-g5h8-x64v-qf5h","MGASA-2026-0137","OESA-2026-3404","RHSA-2026:39547","RHSA-2026:39553","RHSA-2026:39878","RHSA-2026:68632","RHSA-2026:68685","RHSA-2026:68688","RHSA-2026:68693","RLSA-2026:39547","RLSA-2026:39553","RLSA-2026:39878","SUSE-SU-2026:22081-1","SUSE-SU-2026:2324-1","SUSE-SU-2026:2402-1","UBUNTU-CVE-2026-8177","openSUSE-SU-2026:10854-1","openSUSE-SU-2026:20908-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl XML library","requires_auth":"none","summary":"Attacker can cause denial of service by triggering out-of-bounds heap reads in XML::LibXML via truncated UTF-8 node names.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"XML::LibXML versions through 2.0210 for Perl read out-of-bounds heap memory when parsing XML node names containing truncated UTF-8 byte sequences.\n\nA node name ending in the middle of a multi byte UTF-8 sequence causes the parser to read past the end of the input string into adjacent heap memory.\n\nAny Perl process that passes attacker controlled strings to XML::LibXML's DOM node-name methods can reach this path on the default API.
