CWEhttps://cwe.mitre.org/data/definitions/424.html

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).

Weakness

The product does not sufficiently protect all possible paths that a user can take to access restricted functionality or resources.
