Last modified Jun 17, 2026

CVE-2023-0341 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. A stack buffer overflow exists in the ec_glob function of editorconfig-core-c before v0.12.6 which allowed an attacker to arbitrarily write to the stack and possibly allows remote code execution. editorconfig-core-c v0.12.6 resolved this vulnerability by bound checking all write operations over the p_pcre buffer.. EPSS estimates a 0.97% chance of exploitation in the next 30 days.
