CVE-2026-8829
7.5 · HIGHOverview
CVE-2026-8829 is a high-severity vulnerability affecting oalders html\. It was published on June 4, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
HTML::Entities versions before 3.84 for Perl read freed heap memory in _decode_entities.
The XS routine backing HTML::Entities::_decode_entities cached a pointer (repl) into the entity-value SV returned by hv_fetch on the entity2char hash. When the input SV was identical to a value SV in that hash, and that value contained its own key as an entity reference, a later call to grow_gap() reallocated the SV's PV buffer and freed the backing allocation that repl still pointed into. The subsequent copy loop read repl_len bytes from the freed allocation.
The read may disclose adjacent heap contents into the destination SV.
Remediation
Check the references section for vendor advisories and patches from oalders. Update html\ to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
