CVE-2026-62214 Overview
CVE-2026-62214 affects the OpenClaw Bot Framework in versions prior to 2026.5.28. The vulnerability stems from improper input validation of the serviceUrl parameter, allowing lower-trust callers to retrieve bot tokens and authentication credentials. Attackers supply attacker-controlled serviceUrl values through configured input paths, causing the framework to send credentialed requests to endpoints outside the trusted boundary. This behavior enables a Server-Side Request Forgery (SSRF) pattern that exposes sensitive authentication material. The flaw is categorized under [CWE-522] Insufficiently Protected Credentials.
Critical Impact
Successful exploitation exposes bot tokens and service credentials to attacker-controlled hosts, enabling impersonation of the bot and downstream access to integrated services.
Affected Products
- OpenClaw Bot Framework (Node.js) versions prior to 2026.5.28
- Deployments exposing bot endpoints that accept a caller-supplied serviceUrl
- Integrations that forward authentication tokens based on serviceUrl routing

Technical Details for CVE-2026-62214
Vulnerability Analysis
The OpenClaw Bot Framework processes inbound bot activity messages that include a serviceUrl field. This value indicates where the framework should send responses and where it fetches authentication tokens for outbound calls. The framework fails to validate that serviceUrl points to a trusted host before attaching credentials to outbound requests. A lower-trust caller can therefore inject an arbitrary serviceUrl and receive the bot's authentication material at a host they control. The result is an SSRF-adjacent credential leak that undermines the framework's trust boundary between bot channels and the bot service.
Root Cause
The root cause is missing allowlist validation of the serviceUrl parameter. The framework treats any well-formed URL as a legitimate service endpoint. Because credential retrieval and outbound signing are keyed to serviceUrl, an attacker who supplies a malicious value effectively redirects credentialed traffic. This is a classic [CWE-522] weakness compounded by insufficient input validation on a security-relevant control field.
Attack Vector
Exploitation occurs over the network with low attacker privileges and no user interaction. An attacker submits a crafted bot activity or configuration payload containing a serviceUrl value referencing an attacker-owned domain. When the framework processes the message and fetches or attaches its bot token, that credential is transmitted to the attacker endpoint. No verified public proof-of-concept exists at the time of publication.
No verified exploitation code is available. Technical details are described in the VulnCheck SSRF Vulnerability Advisory and the GitHub Security Advisory GHSA-prwc-c6w5-mmgr.
Detection Methods for CVE-2026-62214
Indicators of Compromise
- Outbound HTTP requests from bot framework hosts to unexpected external domains containing Authorization headers or bearer tokens.
- Bot activity messages where the serviceUrl field references domains outside the organization's trusted messaging platforms.
- Unusual token refresh or reuse patterns for the bot's application identity from unfamiliar IP addresses.
Detection Strategies
- Inspect application and reverse-proxy logs for inbound requests containing serviceUrl values that do not match the vendor allowlist (for example, official channel service domains).
- Correlate bot token issuance events with outbound network destinations to flag credentials sent to non-trusted hosts.
- Deploy egress filtering telemetry to identify credentialed calls leaving the bot service to unapproved endpoints.
Monitoring Recommendations
- Enable verbose logging on the Bot Framework connector for the serviceUrl value received on every inbound activity.
- Alert on any use of the bot's client_id from source IPs that are not the bot host.
- Monitor identity provider logs for anomalous token consumption from geographies or ASNs not associated with the bot deployment.
How to Mitigate CVE-2026-62214
Immediate Actions Required
- Upgrade OpenClaw Bot Framework to version 2026.5.28 or later on all deployments.
- Rotate any bot tokens, client secrets, and channel credentials that may have been exposed prior to the upgrade.
- Audit inbound activity logs for serviceUrl values outside the expected messaging channel domains.
Patch Information
The maintainers have released a fixed build in OpenClaw 2026.5.28. Refer to the GitHub Security Advisory GHSA-prwc-c6w5-mmgr for release notes and the code changes that enforce serviceUrl validation.
Workarounds
- Enforce an explicit allowlist of trusted serviceUrl hosts at the reverse proxy or API gateway in front of the bot service.
- Restrict egress from bot framework hosts so that outbound credentialed calls can only reach approved channel service domains.
- Reduce the privileges and scope of the bot's application identity to limit the impact of any leaked token until the patch is applied.
# Configuration example - allowlist trusted serviceUrl hosts at the gateway
# (adjust the domain list to match your approved messaging channels)
ALLOWED_SERVICE_URLS="https://smba.trafficmanager.net/,https://api.trusted-channel.example/"
export ALLOWED_SERVICE_URLS
# Example: reject inbound activities whose serviceUrl is not in the allowlist
# (pseudocode enforced by a middleware or WAF rule)
# if request.body.serviceUrl not in ALLOWED_SERVICE_URLS: return 400
