The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Affected versions of this package are vulnerable to Unchecked Input for Loop Condition when handling \edef
commands. An attacker can cause a near-infinite loop, leading to memory overflow, tying up the main thread, or stack overflow by crafting malicious input using \edef
that bypasses the maxExpand
setting designed to prevent such issues.
Note:
This vulnerability is particularly concerning for users who render untrusted mathematical expressions, as it can be exploited to perform an availability attack, rendering the service unusable.
This vulnerability can be mitigated by forbidding inputs containing the substring "\\edef"
before passing them to the affected package.
