  • IBM has issued a critical security alert regarding a vulnerability in its API Connect platform that could allow attackers to bypass authentication mechanisms and gain unauthorized access to the application. The vulnerability, tracked as CVE-2025-13915, is rated 9.8 out of a maximum of 10.0 on the CVSS scoring system, making it one of the most severe security flaws discovered in recent times.

    According to IBM's bulletin, the shortcoming affects two specific versions of API Connect: 10.0.8.0 through 10.0.8.5 and 10.0.11.0. The vulnerability is described as an authentication bypass flaw, allowing a remote attacker to gain access to the application without proper credentials or authorization.

    The impact of this vulnerability cannot be overstated, as it could potentially allow malicious actors to compromise sensitive data, disrupt operations, or even steal valuable information. Fortunately, IBM has provided a fix for this vulnerability, which customers are advised to download and apply as soon as possible to minimize their exposure to this risk.

    The fix is available on Fix Central, and users are required to extract the files "Readme.md" and "ibm-apiconnect--ifix.13195.tar.gz" before applying the fix based on the appropriate API Connect version. For customers unable to install the interim fix, IBM recommends disabling self-service sign-up on their Developer Portal if enabled, which will help minimize their exposure to this vulnerability.
