Inefficient Regular Expression Complexity Affecting anythingllm package, versions *
Threat Intelligence
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.

NVD Description
Note: Versions mentioned in the description apply only to the upstream anythingllm package and not the anythingllm package as distributed by Minimos.
See How to fix? for Minimos:latest relevant fixed versions and status.
Babel is a compiler for writing next generation JavaScript. When using versions of Babel prior to 7.26.10 and 8.0.0-alpha.17 to compile regular expression named capturing groups, Babel will generate a polyfill for the .replace method that has quadratic complexity on some specific replacement pattern strings (i.e. the second argument passed to .replace). Generated code is vulnerable if all the following conditions are true: Using Babel to compile regular expression named capturing groups, using the .replace method on a regular expression that contains named capturing groups, and the code using untrusted strings as the second argument of .replace. This problem has been fixed in @babel/helpers and @babel/runtime 7.26.10 and 8.0.0-alpha.17. It's likely that individual users do not directly depend on @babel/helpers, and instead depend on @babel/core (which itself depends on @babel/helpers). Upgrading to @babel/core 7.26.10 is not required, but it guarantees use of a new enough @babel/helpers version. Note that just updating Babel dependencies is not enough; one will also need to re-compile the code. No known workarounds are available.
