Affected: wagtail

Wagtail is an open source content management system built on Django. A bug in Wagtail's `parse_query_string` would result in it taking a long time to process suitably crafted inputs. When used to parse sufficiently long strings of characters without a space, `parse_query_string` would take an unexpectedly large amount of time to process, resulting in a denial of service. In an initial Wagtail installation, the vulnerability can be exploited by any Wagtail admin user. It cannot be exploited by end users. If your Wagtail site has a custom search implementation which uses `parse_query_string`, it may be exploitable by other users (e.g. unauthenticated users). Patched versions have been released as Wagtail 5.2.6, 6.0.6 and 6.1.3.

### Impact

A bug in Wagtail's [`parse_query_string`](https://docs.wagtail.org/en/stable/topics/search/searching.html#wagtailsearch-query-string-parsing) would result in it taking a long time to process suitably crafted inputs. When used to parse sufficiently long strings of characters without a space, `parse_query_string` would take an unexpectedly large amount of time to process, resulting in a denial of service.

In an initial Wagtail installation, the vulnerability can be exploited by any Wagtail admin user. It cannot be exploited by end users. If your Wagtail site has a custom search implementation which uses `parse_query_string`, it may be exploitable by other users (e.g. unauthenticated users).

### Patches

Patched versions have been released as Wagtail 5.2.6, 6.0.6 and 6.1.3.

This vulnerability affects all unpatched versions from Wagtail 2.0 onwards.

### Workarounds

Site owners who are unable to upgrade to a patched version can limit the length of search terms passed to `parse_query_string`. Whilst the performance characteristics will depend on your hosting environment, 1000 characters has been shown to still be fairly fast, without triggering this vulnerability.

No workaround is available for the Wagtail admin usage.
