Description
OpenClaw versions before 2026.5.28 Bot Framework contains an improper input validation vulnerability that allows lower-trust callers to expose bot tokens and credentials by failing to properly validate serviceUrl parameters. Attackers can supply malicious serviceUrl values through configured input paths to retrieve sensitive authentication data outside the trusted boundary.
