GHSA-v6c5-9mp4-mwq4 PUBLISHED CVSS 7.699999809265137 HIGH

Record from GitHub Advisory Database · Published November 26, 2025

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.
