GoClaw Privilege and Command Injection Flaws

OS command injection in nextlevelbuilder GoClaw through version 3.11.3 allows remote attackers to execute arbitrary shell commands inside the sandbox container by supplying a crafted file path to the write_file tool. The flaw exists in FsBridge.WriteFile (internal/sandbox/fsbridge.go), which interpolated the destination path into a shell command (`sh -c "cat > <path>"`) executed via docker exec, letting shell metacharacters such as `$(...)` break out of the intended write operation. Publicly available exploit code exists and the upstream patch is still pending merge at the time of analysis, raising real-world risk despite a moderate 7.3 CVSS.

Improper privilege management in nextlevelbuilder GoClaw up to version 3.11.3 allows authenticated low-privileged users to escalate privileges via the handleSave function of the RoleAdmin Gateway component (internal/http/tts_config.go). The vulnerability is remotely exploitable over the network with no user interaction required, though a low-privilege authenticated session is a prerequisite per the CVSS:4.0 vector (PR:L). A publicly available proof-of-concept exists (published via GitHub issue #1118), but this CVE has not been added to the CISA KEV catalog. The CVSS 4.0 base score of 2.1 (LOW) reflects constrained confidentiality, integrity, and availability impact with no scope change to downstream systems.

Improper authorization in GoClaw (nextlevelbuilder/goclaw) up to version 3.11.3 allows a remote low-privileged attacker to bypass authorization controls via the `auth` function in `internal/http/evolution_handlers.go`. The CVSS 4.0 score is 2.1 with limited integrity and availability impact and no confidentiality exposure. A public proof-of-concept exploit has been disclosed via a GitHub issue, though the project has not been confirmed as actively exploited in the wild per CISA KEV.
