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-2026-88816 in the wild and no public exploit code.\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-2026-88816/ (Markdown: https://insights.sbomify.com/CVE-2026-88816/index.md)","id":"CVE-2026-88816","markdown":"https://insights.sbomify.com/CVE-2026-88816/index.md","name":"CVE-2026-88816","record":{"aliases":["AZL-105215","BELL-CVE-2026-88816","DEBIAN-CVE-2026-88816","ECHO-5f1f-bfbe-e4bd","GHSA-f4qx-mr9m-q2hq","MINI-jqpv-j697-w57r","UBUNTU-CVE-2026-88816"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl DBI library","requires_auth":"none","summary":"An attacker can cause a segmentation fault and denial of service by setting the FetchHashKeyName attribute to a numeric value in the Perl DBI library.","user_interaction":"not_required","vuln_class":"null_dereference"},"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-843","name":"Access of Resource Using Incompatible Type"}],"description":"DBI versions before 1.654 for Perl incorrectly treat numeric values as strings in FetchHashKeyName.\n\nfetchrow_hashref uses the string pointer of the FetchHashKeyName attribute as the key name without stringifying it first.
