CVE-2025-13601

HIGHCVSS 7.7/10EPSS 0.31%

Last modified

CVE-2025-13601 is a high-severity vulnerability rated 7.7/10 on the CVSS scale. A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string.. EPSS estimates a 0.31% chance of exploitation in the next 30 days.
