CVE-2026-34080

A flaw was found in xdg-dbus-proxy, a filtering proxy for D-Bus connections. A local client can exploit a policy parser vulnerability by crafting specific policy rules, such as including a space before the equals sign in "eavesdrop=true". This improper parsing allows the client to bypass intended...
