The highlighting functionality in geshi.php in GeSHi before 1.0.8 allows remote attackers to cause a denial of service (infinite loop) via an XML sequence containing an opening delimiter without a closing delimiter, as demonstrated using "<".
Does this matter?
A public exploit is published in Exploit-DB (verified), so the technical barrier is gone even though the severity is medium and EPSS is 3.9%. Treat it as high on anything reachable from the internet.
