CVE-2026-86145
Last modified
CVE-2026-86145 is a high-severity vulnerability rated 8.2/10 on the CVSS scale. PCRE2 before 10.48 allows a pcre2_dfa_match out-of-bounds write because reuse of a cached workspace block, in a recursive DFA matching workspace, lacks a size check (even though a newly allocated block, for the same purpose, does have a size check). This outcome requires an attacker-controlled regular expression, or a recursive pattern in conjunction with a small heap limit (this can be set through the API).. EPSS estimates a 0.37% chance of exploitation in the next 30 days.
