Last modified Jun 17, 2026

CVE-2015-2325 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The compile_branch function in PCRE before 8.37 allows context-dependent attackers to compile incorrect code, cause a denial of service (out-of-bounds heap read and crash), or possibly have other unspecified impact via a regular expression with a group containing a forward reference repeated a large number of times within a repeated outer group that has a zero minimum quantifier.. EPSS estimates a 1.57% chance of exploitation in the next 30 days.
