Summary

CVE-2026-100603 is a high-severity Improper Control of Interaction Frequency (CWE-799) vulnerability. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 20th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-10 (Concurrent Session Control) and AC-7 (Unsuccessful Logon Attempts) — see the control section below for these in your framework.

Vulnerability Data

ClawHub (openclaw/clawhub) application/backend contains a flaw in the skill report moderation flow: four distinct ordinary authenticated accounts can report a visible skill and trigger automatic hiding (moderationStatus: hidden) of that skill from the catalog without any moderator decision. Because the…

reporter quota counts only reports filed against visible targets, the same accounts can repeat the process against additional skills; official skills are not exempt. The issue was confirmed at revision cbfee7343ddc867316dd9b3de6fa8856730f9f41; the complete historical affected range was not established. The fix (PR #3681) is included in revision 8c2de6c506bb4efabe3f0c2ffb8370b9e23d4650; self-hosted deployments should update to that revision or a later descendant. The npm CLI and OpenClaw runtime are separate products and are not affected.

MITRE ATT&CK Enterprise Techniques

T1110 Brute Force Credential Access
Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.
T1110.001 Password Guessing Credential Access
Adversaries with no prior knowledge of legitimate credentials within the system or environment may guess passwords to attempt access to accounts.
T1110.003 Password Spraying Credential Access
Adversaries may use a single or small list of commonly used passwords against many different accounts to attempt to acquire valid account credentials.
T1110.004 Credential Stuffing Credential Access
Adversaries may use credentials obtained from breach dumps of unrelated accounts to gain access to target accounts through credential overlap.
T1498 Network Denial of Service Impact
Adversaries may perform Network Denial of Service (DoS) attacks to degrade or block the availability of targeted resources to users.
T1499 Endpoint Denial of Service Impact
Adversaries may perform Endpoint Denial of Service (DoS) attacks to degrade or block the availability of services to users.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

ac-10 enforces a hard limit on concurrent sessions per user, directly stopping uncontrolled interaction frequency at the session level.

ac-7 directly enforces a limit on the frequency of invalid authentication attempts, structurally preventing the weakness for that interaction class.

sc-5 reduces the impact of excessive request volume (DoS) but does not itself impose the frequency controls whose absence defines the weakness.

prevents

Application security requirements explicitly include controls on interaction frequency and throttling.

prevents

Secure architecture principles recommend rate-limiting and resource-management mechanisms.

prevents

Secure coding practices can embed input-frequency and throttling checks in code.

degrades

Capacity management directly limits request rates and resource exhaustion that CWE-799 describes.
