CVE-2024-13926
The WP-Syntax WordPress plugin through 1.2 does not properly handle input, allowing an attacker to create a post containing a large number of tags, thereby exploiting a catastrophic backtracking issue in the regular expression processing to cause a DoS.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.47%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
