CVE	Summary	Severity	CVSS	EPSS	Priority	Signals
CVE-2026-10219	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.	MEDIUM	5.5	0.8%	48	PoC
CVE-2026-10617	Missing authentication in GoClaw's Webhook Verification Handler allows unauthenticated remote attackers to interact with webhook endpoints without valid credentials, affecting all versions up to and including 3.11.3. The flaw resides in the `resolveAuth` function within `internal/http/auth.go`, where the authentication check can be bypassed entirely. A publicly available exploit has been disclosed (GitHub issue #1134), and the project acknowledges the issue as a bug; no confirmed patched release has been identified at time of analysis.	MEDIUM	5.5	0.1%	48	PoC No patch
CVE-2026-7505	Improper authorization in the GoClaw and GoClaw Lite RPC gateway allows unauthenticated remote attackers to invoke privileged methods including configuration exfiltration, heartbeat manipulation, and agent mutation via WebSocket connections. Versions up to 3.8.5 implement a fail-open authorization policy where unclassified RPC methods default to viewer-level access and authentication failures fall back to authenticated viewer sessions. Public exploit code exists (GitHub issue #866) demonstrating unauthorized method invocation. Vendor-released patch: version 3.9.0 implements fail-closed authorization with explicit method classification and rejects connections lacking valid credentials.	MEDIUM	5.5	0.0%	48	PoC
CVE-2026-16124	Server-side request forgery in GoClaw through 3.15.0-beta.32 allows authenticated remote attackers to bypass the SSRF blocklist in the web_fetch component by targeting IP addresses in the RFC 2544 benchmarking range (198.18.0.0/15) and the reserved-for-future-use range (240.0.0.0/4), which the `isPrivateIP` function in `internal/tools/web_shared.go` failed to block. A publicly available proof-of-concept exploit exists (GitHub issue #1218, corroborated by E:P in the CVSS 4.0 vector), though no CISA KEV entry confirms active widespread exploitation. The bypass is constrained by a PR:L requirement and by the rarity of infrastructure that routes these non-standard ranges to reachable internal services.	LOW	2.1	0.3%	31	PoC
CVE-2026-15626	Path traversal in GoClaw 3.13.3-beta.3 allows authenticated remote attackers to read or write files outside the intended workspace directory by manipulating the path argument to the `writeFile` function in the ACP ToolBridge Workspace Handler (`internal/providers/acp/tool_bridge.go`). A proof-of-concept exploit has been publicly disclosed via a GitHub issue, lowering the bar for exploitation. No CISA KEV listing indicates active widespread exploitation has not been confirmed at time of analysis.	LOW	2.1	0.3%	31	PoC No patch
CVE-2026-16119	Incorrect authorization in GoClaw's WebSocket Approval Endpoint allows low-privileged remote attackers to bypass access controls in the RequestApproval function, potentially approving privileged operations without proper authorization. All versions up to and including 3.13.2 of nextlevelbuilder/goclaw are affected. A public exploit has been disclosed via GitHub, though no CISA KEV listing confirms active exploitation at this time.	LOW	2.1	0.3%	31	PoC No patch
CVE-2026-14716	Incorrect authorization in nextlevelbuilder GoClaw's WebSocket RPC Handler allows authenticated low-privilege remote attackers to bypass access controls on restricted methods. Affects all versions up to and including 3.13.0-beta.2. No public exploit identified as actively exploited (not in CISA KEV), but a publicly available proof-of-concept exists, lowering the barrier for exploitation against any exposed GoClaw deployment.	LOW	2.1	0.2%	31	PoC No patch
CVE-2026-16120	Name resolution bypass in GoClaw's exec approval subsystem allows remote low-privileged attackers to circumvent the binary execution allowlist. Affecting all versions up to and including 3.13.3-beta.3, the flaw resides in the matchesAllowlist and extractBin functions within internal/tools/exec_approval.go, where crafted input causes the allowlist check to resolve a name or reference incorrectly, permitting unauthorized binary execution. A publicly disclosed proof-of-concept exploit exists (GitHub issue #1213); no CISA KEV listing is present, indicating no confirmed widespread active exploitation at time of analysis.	LOW	2.1	0.2%	31	PoC No patch
CVE-2026-15624	Server-side request forgery in GoClaw 3.13.3-beta.3 enables authenticated remote attackers to manipulate the `output.video_url` parameter within the `bytePlusDownloadVideo` function, coercing the server into issuing HTTP requests to attacker-controlled destinations including internal network resources. The flaw resides in `internal/tools/create_video_byteplus.go` at the invoke endpoint. A proof-of-concept exploit has been publicly disclosed via GitHub issue #1199; however, no CISA KEV listing confirms mass active exploitation, and the CVSS 4.0 score of 2.1 reflects the low-privilege authentication barrier and limited per-request impact scope.	LOW	2.1	0.2%	31	PoC No patch
CVE-2026-16121	Improper authorization in nextlevelbuilder GoClaw up to version 3.13.2 allows remote low-privilege authenticated attackers to bypass binary execution controls by manipulating the isSafeBin function in internal/tools/exec_approval.go. The authorization logic flaw permits approval of binaries that should be restricted, with potential for unauthorized code execution within the tool's operational context - particularly impactful in pipeline or build automation deployments. A publicly available proof-of-concept exists (CVSS 4.0 E:P); the vulnerability is not listed in CISA KEV, indicating no confirmed widespread active exploitation at time of analysis.	LOW	2.1	0.2%	31	PoC No patch
CVE-2026-16123	Missing authorization on the Invoke Endpoint in nextlevelbuilder GoClaw up to version 3.13.2 allows low-privileged remote attackers to invoke tool functionality without proper permission checks. The flaw resides in the `ToolsInvokeHandler.ServeHTTP` function within `internal/http/tools_invoke.go`, where authorization is absent rather than bypassed cryptographically. A public proof-of-concept exploit is available via GitHub, lowering the bar for exploitation; however, this CVE is not currently listed in the CISA KEV catalog, so confirmed active exploitation has not been established at time of analysis.	LOW	2.1	0.2%	31	PoC No patch
CVE-2026-16199	Improper authorization in nextlevelbuilder GoClaw up to version 3.13.3-beta.3 allows low-privileged remote attackers to bypass access controls via manipulation of the ExecTool.Execute function in credentialed_exec.go. The CVSS 4.0 vector confirms network-accessible exploitation requiring only low-privilege credentials, with limited but confirmed confidentiality, integrity, and availability impact on the vulnerable system. A publicly available proof-of-concept exploit exists (tracked in GitHub issue #1215), though the overall CVSS 4.0 base score of 2.1 reflects constrained real-world impact.	LOW	2.1	0.2%	31	PoC No patch
CVE-2026-7595	Code injection vulnerability in nextlevelbuilder ui-ux-pro-max-skill up to 2.5.0 allows authenticated remote attackers to execute arbitrary code via unsanitized plugin names in the Tailwind Config Generator. The _format_plugins function constructs require() statements without validation, enabling attackers with login credentials to inject malicious JavaScript into the Tailwind configuration. Publicly available exploit code exists and the vendor has released a patch via pull request, though adoption status is unconfirmed.	LOW	2.1	0.1%	31	PoC
CVE-2026-10217	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.	LOW	2.1	0.0%	31	PoC No patch
CVE-2026-10218	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.
