CVE-2026-17532: Seraphinite HMAC type juggling exposes unauthenticated reflected XSS

Seraphinite Accelerator through 2.29.18 accepts seraph_accel_prep JSON in which the attacker supplies boolean true as nonce. CacheExtractPreparePageParams() uses a loose comparison against the expected HMAC, so the boolean can compare equal to a non-empty signature. The attacker-controlled selfTest value then reaches _CbContentFinishSkip(), which concatenates it into the HTML response without escaping, producing reflected JavaScript execution when a victim follows a crafted link. The CNA does not disclose the public route. Its prose stops at 2.29.15, but the structured affected data includes 2.29.18 and the linked fix follows that later tag.

Mar 04, 2026	CVE-2026-3058 Seraphinite Accelerator: Sensitive information exposure Seraphinite Accelerator is affected by sensitive information exposure. Exploitation requires an authenticated subscriber account. Successful exploitation can disclose data that should not be available to the caller. The public source does not disclose the vulnerable endpoint, action, parameter or function, so the precise input path remains unknown.	See mitigation notes	CVE4.3 NVD6.5
Mar 04, 2026	CVE-2026-3056 Seraphinite Accelerator: A security weakness Seraphinite Accelerator is affected by a security weakness. Exploitation requires an authenticated subscriber account. The resulting impact depends on how the affected component exposes the vulnerable operation. The public source does not disclose the vulnerable endpoint, action, parameter or function, so the precise input path remains unknown.	See mitigation notes	CVE4.3 NVDPending
Feb 20, 2026	CVE-2024-54222 Seraphinite Accelerator: A security weakness Seraphinite Accelerator is affected by a security weakness. Exposure depends on how the affected operation is made reachable by the site. The resulting impact depends on how the affected component exposes the vulnerable operation. The public source does not disclose the vulnerable endpoint, action, parameter or function, so the precise input path remains unknown.	See mitigation notes	CVE4.3 NVDPending
Jun 14, 2025	CVE-2025-6059 Seraphinite Accelerator: Cross-site request forgery Seraphinite Accelerator is affected by cross-site request forgery. The vulnerable path is reachable without authentication. Exploitation relies on a signed-in privileged user submitting an attacker-controlled request. The public source does not disclose the vulnerable endpoint, action, parameter or function, so the precise input path remains unknown.	See mitigation notes	CVE4.3 NVDPending
Mar 28, 2024	CVE-2024-22138 Seraphinite Accelerator: A security weakness Seraphinite Accelerator is affected by a security weakness. Exposure depends on how the affected operation is made reachable by the site. The resulting impact depends on how the affected component exposes the vulnerable operation. The public source does not disclose the vulnerable endpoint, action, parameter or function, so the precise input path remains unknown.	See mitigation notes	CVE5.3 NVDPending
Feb 28, 2024	CVE-2024-1568 Seraphinite Accelerator: Server-side request forgery Seraphinite Accelerator is affected by server-side request forgery. Exploitation requires an authenticated subscriber account. The vulnerable server can be induced to make attacker-selected network requests. The public source does not disclose the vulnerable endpoint, action, parameter or function, so the precise input path remains unknown.	See mitigation notes	CVE6.4 NVD6.4
Dec 14, 2023	CVE-2023-49740 Seraphinite Accelerator: Cross-site scripting Seraphinite Accelerator is affected by cross-site scripting. Exposure depends on how the affected operation is made reachable by the site. Injected script can execute in the affected site's origin when the vulnerable output is viewed. The public source does not disclose the vulnerable endpoint, action, parameter or function, so the precise input path remains unknown.	See mitigation notes	CVE7.1 NVD6.1
Nov 27, 2023	CVE-2023-5611 Seraphinite Accelerator: Cross-site request forgery Seraphinite Accelerator is affected by cross-site request forgery. The vulnerable path is reachable without authentication. Exploitation relies on a signed-in privileged user submitting an attacker-controlled request. The public source does not disclose the vulnerable endpoint, action, parameter or function, so the precise input path remains unknown.	See mitigation notes	CVEPending NVD5.3
Nov 20, 2023	CVE-2023-5610 Seraphinite Accelerator: A security weakness Seraphinite Accelerator is affected by a security weakness. Exposure depends on how the affected operation is made reachable by the site. The resulting impact depends on how the affected component exposes the vulnerable operation. The public source does not disclose the vulnerable endpoint, action, parameter or function, so the precise input path remains unknown.	See mitigation notes	CVEPending NVD5.4
Nov 20, 2023	CVE-2023-5609 Seraphinite Accelerator: Cross-site scripting Seraphinite Accelerator is affected by cross-site scripting. Exposure depends on how the affected operation is made reachable by the site. Injected script can execute in the affected site's origin when the vulnerable output is viewed. The public source does not disclose the vulnerable endpoint, action, parameter or function, so the precise input path remains unknown.	See mitigation notes	CVEPending NVD6.1
