Summary

diem-project diem is a rolling release, and the sources identify affected releases only by commit 116974edfb9a5b8bd69cb13586dc62bcdbb485ad, with no version numbers. Manipulating the text argument of the dmBaseLinkTag::text function in the dmWidget component does not neutralize input, which causes cross-site scripting (CWE-79). A remote attacker with low privileges can trigger it, and a public exploit has been released.
