Apache Traffic Server versions 8.0.0 through 8.1.9, 9.0.0 through 9.2.14, and 10.0.0 through 10.1.3 contain a Server-Side Request Forgery (SSRF) vulnerability. This occurs due to a redirect-limit bypass when plugins reset the retry counter, enabling SSRF amplification. The issue is fixed in versions 9.2.15 and 10.1.4.
AI Analysis
Technical Summary
CVE-2026-58189 is a Server-Side Request Forgery (SSRF) vulnerability in Apache Traffic Server. The vulnerability arises because plugins can reset the retry counter, allowing an attacker to bypass the redirect limit and amplify SSRF attacks. This affects Apache Traffic Server versions from 8.0.0 through 8.1.9, 9.0.0 through 9.2.14, and 10.0.0 through 10.1.3. Upgrading to versions 9.2.15 or 10.1.4 mitigates the issue.
Potential Impact
The vulnerability allows SSRF amplification by bypassing the redirect limit, which can lead to denial of service (availability impact) as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). There is no direct confidentiality or integrity impact reported.
Mitigation Recommendations
