The Enterprise Security API (ESAPI) project is an OWASP project
to create simple strong security controls for every web platform.
Security controls are not simple to build. You can read about the
hundreds of pitfalls for unwary developers on the OWASP web site. By
providing developers with a set of strong controls, we aim to
eliminate some of the complexity of creating secure web applications.
This can result in significant cost savings across the SDLC.
The Validator.isValidSafeHTML method can result in false negatives where it reports some input as safe (i.e., returns true), but really isn't, and using that same input as-is can in certain circumstances result in XSS vulnerabilities. Because this method cannot be fixed, it is being deprecated and will be removed in one years time from when this advisory is published.
Note that all versions of ESAPI, that have this method (which dates back to at least the ESAPI 1.3 release more than 15 years ago) have this issue and it will continue to exist until these two methods are removed in a future ESAPI release.
:heavy_check_mark: This issue was automatically closed by Mend because the vulnerable library in the specific branch(es) was either marked as ignored or it is no longer part of the Mend inventory.
