Exploitation Conditions

Exploitation requires an authenticated lower-trust caller (CVSS PR:L) who can interact with OpenClaw's isolated cron job feature, plus the specific attack requirement (AT:P) that the cron job's input paths are misconfigured/mishandled so that path resolution can be manipulated to reload denied execution tools. The concrete prerequisite named in the description is access to the affected cron feature with controllable input paths on OpenClaw 2026.6.1-2026.6.8. Limiting factors: the attacker must already possess a low-privilege authenticated foothold (not unauthenticated), the target must run a vulnerable version with the cron feature in use, and impact is confined to the vulnerable OpenClaw system (SC/SI/SA:N) rather than pivoting to other systems; no user interaction is required (UI:N).

Impact

The vendor CVSS 4.0 vector (AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N, 7.7) describes a network-reachable, low-complexity attack that nonetheless requires an existing low-privilege foothold (PR:L) and the presence of a specific attack requirement (AT:P) - the misconfigured input-path condition in the cron feature. High confidentiality, integrity, and availability impact on the vulnerable system are offset by unchanged subsequent-system metrics (SC/SI/SA:N), meaning damage is contained to the OpenClaw instance rather than cascading. No EPSS score was supplied, the CVE is not in CISA KEV, and no POC was referenced, so all real-world exploitation signals are currently absent or unknown - this reads as a genuine authorization weakness but not an urgent mass-exploitation event. The AT:P requirement and PR:L precondition are the key limiters: an attacker must already be an authenticated lower-trust caller and the target must expose the affected cron configuration, suggesting targeted rather than opportunistic risk. Note the assessment relies solely on the vendor vector and a two-sentence description; the exact nature of the 'misconfigured input paths' is not detailed in the input.

Exploit ScenarioDerived

An attacker who already holds a low-trust authenticated account on an OpenClaw instance schedules or edits an isolated cron job, supplying crafted input paths that cause the cron execution context to load execution tools their role was denied. Once those tools are restored, they run privileged actions or plant a persistent scheduled job that continues executing beyond their authorization. No public exploit code has been identified, and success depends on the specific misconfigured-input-path condition (AT:P) being present.

AnalysisAIv1 – Jul 17, 2026

Privilege escalation in OpenClaw's isolated cron job feature (versions 2026.6.1 through 2026.6.8) lets a lower-trust authenticated caller reclaim execution tools that authorization policy had explicitly denied, enabling actions and persistence beyond their intended trust level. The flaw is an incorrect-authorization (CWE-863) issue rooted in misconfigured input path handling within the cron subsystem, and carries a CVSS 4.0 score of 7.7. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.

RemediationAI

Vendor-released patch: upgrade OpenClaw to version 2026.6.9 or later, which closes the fix range stated in the advisory; this is the primary and recommended remediation. Consult the GitHub Security Advisory at https://github.com/openclaw/openclaw/security/advisories/GHSA-mm9g-83wh-mhwj for exact upgrade guidance and the VulnCheck advisory at https://www.vulncheck.com/advisories/openclaw-privilege-escalation-via-cron for corroborating detail. If immediate upgrade is not possible, reduce exposure by disabling or restricting the isolated cron feature for lower-trust accounts, auditing and locking down the cron input path configuration so callers cannot influence tool resolution, and tightening which principals hold the low-privilege role that can schedule cron jobs - with the trade-off that disabling cron removes scheduled-job functionality and restricting roles may disrupt legitimate automation. Because the fix version is explicitly known, prioritize patching over workarounds.

Technical ContextAI · show details

OpenClaw exposes an isolated cron feature intended to run scheduled jobs under a constrained set of permitted execution tools, sandboxing lower-trust callers away from privileged operations. The vulnerability is classed as CWE-863 (Incorrect Authorization): the authorization decision that should keep a caller's denied tools out of reach is not correctly enforced when the cron job resolves its input paths. Because the input paths are misconfigured/mishandled, a caller can influence which tools the cron execution context loads, effectively re-granting denied capabilities. The single affected component is identified by CPE cpe:2.3:a:openclaw:openclaw:*:*:*:*:*:*:*:*, and VulnCheck's tags (Authentication Bypass, Privilege Escalation) reinforce that the defect is an enforcement gap in the trust boundary rather than a memory-safety or injection bug.

DescriptionCVE.org

OpenClaw versions 2026.6.1 before 2026.6.9 contain a privilege escalation vulnerability in isolated cron jobs that allows lower-trust callers to regain denied execution tools. Attackers can execute or persist actions beyond their intended authorization by leveraging misconfigured input paths in the affected cron feature.

Executive ViewAI

Why It Matters

OpenClaw versions 2026.6.1 through 2026.6.8 contain an access control bypass in cron job execution that allows authenticated users to execute actions prohibited by policy, creating an insider threat risk and enabling unauthorized system persistence. This vulnerability directly compromises the ability to enforce separation of duties for scheduled job execution across the organization. Immediate containment measures are required until patches become available.

Business Impact: High
Compensating Controls

Restrict cron job configuration and execution capabilities to administrative users only. Implement enhanced monitoring and alerting for all cron job modifications and executions. Conduct regular audits of scheduled job definitions to detect unauthorized additions or modifications. Enforce strict least-privilege access controls for system accounts.
