Summary
MemTensor memmy-agent up to 1.0.9, 1.1.1 and 1.2.2 has a flaw in the requireAdminWrite function of the Memory Service HTTP server. The server accepts unauthenticated requests to its shutdown endpoint when no token is configured, which lets a remote attacker cause resource consumption (CWE-400) through a victim's browser, and the attack is considered high complexity. A public exploit is linked in the references.

Description from the CNA
A weakness has been identified in MemTensor memmy-agent up to 1.0.9/1.1.1/1.2.2. The impacted element is the function requireAdminWrite of the file Memory/src/server/http.ts of the component Memory Service. This manipulation causes resource consumption. Remote exploitation of the attack is possible. The attack is considered to have high complexity. The exploitability is regarded as difficult. The exploit has been made available to the public and could be used for attacks. The exploit is partially overstated. While "POST /api/v1/admin/shutdown" accepts unauthenticated requests when no token is configured, it’s designed for local use and later received cross-origin fixes. Unauthenticated endpoint exposure is confirmed; browser-triggered DoS remains likely but depends on specific browser behavior.
