Details

As written in the advisory (Markdown source, shown as plain text).

### Impact Nautobot UI object-bulk-rename endpoints (for example, `/dcim/interfaces/rename/`) were vulnerable to application-wide denial of service via maliciously crafted regular expressions in the `find` field in combination with the `use_regex` flag. ### Patches A general-purpose timeout has been added to these endpoints in Nautobot v2.4.33 and v3.1.2, which ensures that the request will fail early with an appropriate message if regular expression evaluation takes more than a short period of time, instead of continuing to execute for an indefinite duration. ### Workarounds No known workaround has been identified at this time. ### References - 2.4.33 (<a href="https://github.com/nautobot/nautobot/commit/c2b766966d814a7141f62c7bc90c85fefb7892ee">patch</a>) - 3.1.2 (<a href="https://github.com/nautobot/nautobot/commit/5a30d0916953afbeedd24a784709e762cc3879cd">patch</a>)
