Denylisted command autoexecution via uncanonicalized environment prefixes
Published Jun 24, 2026 · Updated Jun 24, 2026
Command execution permission-check bypass in Warp allows context-dependent attackers to run denylisted shell commands without confirmation. The BlocklistAIPermissions denylist path evaluated raw subcommands before stripping leading environment-variable assignments, so a prefix such as X=1 hid a blocked base command. Exploitation requires the victim to run the default unsandboxed CLI agent on attacker-controlled or prompt-injectable context, and commands execute with the victim user's local shell authority.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
