Description Christopher Fore 2025-03-22 00:03:19 UTC

A vulnerability was found in Mercurial SCM 4.5.3/71.19.145.211. It has been declared as problematic. This vulnerability affects unknown code of the component Web Interface. The manipulation of the argument cmd leads to cross site scripting. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.



The above is fixed in 6.9.4.

The patch is https://foss.heptapod.net/mercurial/mercurial-devel/-/commit/a5c72ed2929341d97b11968211c880854803f003

As it is quite large especially for the tests part. I think it will be simpler to quickly stabilize the version 6.9.4.
