CVE-2026-71272

Summary

The flaw lies in the safeDialContext function of Memos' webhook dispatch, which fails to use validated IP addresses for network connections, potentially allowing attackers to exploit DNS resolution to execute unauthorized actions.

Exploitability

Exploitation is moderately hard as it requires control over DNS resolution, but preconditions include network access and knowledge of the target's internal IP ranges.

Blast radius

If exploited, the impact could be significant, as it allows attackers to bypass IP validation and potentially execute arbitrary code or perform unauthorized actions.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Disable the affected webhook feature or ensure that only trusted DNS resolvers are used, and update to the latest version of Memos if a patch is available.
