AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
AV:N and PR:N confirmed by unauthenticated HTTP token submission; A:H reflects full pod memory exhaustion; C:N and I:N as no data access or modification occurs.

Lifecycle Timeline
2DescriptionCVE.org
A flaw was found in search-v2-api. An unauthenticated attacker can exploit this by sending requests with unique random bearer tokens. Each unique token creates a permanent entry in the unbounded tokenReviews cache, which is not properly cleared. This can lead to memory exhaustion of the search-api pod, resulting in a Denial of Service (DoS).
AnalysisAI
Memory exhaustion in Red Hat Advanced Cluster Management for Kubernetes 2's search-v2-api component allows unauthenticated remote attackers to crash the search-api pod by submitting HTTP requests with unique random bearer tokens. Each unique token creates a permanent, uncleaned entry in the unbounded tokenReviews cache; sustained submission accumulates entries until the pod exhausts available memory and is killed. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The search-v2-api must be reachable by the attacker over the network, which is confirmed by the CVSS vector's AV:N (network attack vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.5 High score reflects a straightforward risk picture: network-accessible, zero-authentication, low-complexity DoS. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with network access to the RHACM cluster's search-api endpoint writes a trivial script that generates a high volume of HTTP requests, each carrying a distinct randomly generated bearer token string. As the script runs, the search-v2-api processes each token, creates a permanent entry in the tokenReviews cache, and never evicts them. … |
| Remediation | No specific patched version has been identified in the available data - the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-71469 and Bugzilla ticket #2512148 should be monitored for a confirmed fix version and should be applied as soon as one is released. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Red Hat Advanced Cluster Management for Kubernetes 2 deployments, confirm current product versions, and begin isolating the search-v2-api component from untrusted networks; note that no public exploit identified at time of analysis, though attack feasibility is high given unauthenticated access and low complexity requirements. …
