Singapore Cyber Company Warns of Crucial IBM API Join Vulnerability (CVE-2025-13915)
A essential authentication bypass flaw, CVE-2025-13915, impacts IBM API Join. Singapore points alert as IBM releases fixes.
Overview
The Cyber Safety Company of Singapore has issued an alert relating to a essential vulnerability affecting IBM API Join, following the discharge of official safety updates by IBM on 2 January 2026. The flaw, tracked as CVE-2025-13915, carries a CVSS v3.1 base rating of 9.8, putting it among the many most extreme vulnerabilities presently disclosed for enterprise automation software program.
In keeping with IBM’s safety bulletin, the difficulty stems from an authentication bypass weak point that would permit a distant attacker to realize unauthorized entry to affected methods with out legitimate credentials. The vulnerability impacts a number of variations of IBM API Join, a extensively used platform for managing software programming interfaces throughout enterprise environments.
Particulars of CVE-2025-13915 and Technical Affect
IBM confirmed that CVE-2025-13915 was recognized by means of inside testing and labeled underneath CWE-305: Authentication Bypass by Main Weak spot. The flaw permits authentication mechanisms to be bypassed, regardless of the underlying authentication algorithm itself being sound. The weak point arises from an implementation flaw that may be exploited independently.
The official CVSS vector for the vulnerability is:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
This signifies that the vulnerability is remotely exploitable, requires no consumer interplay, and may result in a full compromise of confidentiality, integrity, and availability. IBM said that profitable exploitation may allow attackers to entry the appliance remotely and function with unauthorized privileges.
Knowledge from Cyble Imaginative and prescient additional classifies the difficulty as “very essential,” confirming that IBM API Join as much as variations 10.0.8.5 and 10.0.11.0 is affected.
Affected IBM API Join Variations
IBM confirmed that the next variations are susceptible to CVE-2025-13915:
- IBM API Join V10.0.8.0 by means of V10.0.8.5
- IBM API Join V10.0.11.0
No proof has been disclosed indicating lively exploitation within the wild, and the vulnerability will not be presently listed within the CISA Recognized Exploited Vulnerabilities (KEV) catalog.
Cyble Imaginative and prescient information additionally signifies that the vulnerability has not been mentioned in underground boards, suggesting no recognized public exploit circulation presently.
The EPSS rating for CVE-2025-13915 stands at 0.37, indicating a average likelihood of exploitation in comparison with different high-severity vulnerabilities.
Remediation and Mitigation Steering
IBM has launched interim fixes (iFixes) to handle the vulnerability and strongly recommends that affected organizations apply updates instantly. For IBM API Join V10.0.8, fixes can be found for every sub-version from 10.0.8.0 by means of 10.0.8.5. A separate interim repair has additionally been launched for IBM API Join V10.0.11.0.
IBM’s advisory explicitly states:
“IBM strongly recommends addressing the vulnerability now by upgrading.”
For environments the place fast patching will not be potential, IBM advises directors to disable self-service sign-up on the Developer Portal, if enabled. This mitigation may also help scale back publicity by limiting potential abuse paths till updates could be utilized.
Cyble Imaginative and prescient reinforces this suggestion, noting that upgrading removes the vulnerability totally, and that non permanent mitigations ought to solely be thought of short-term threat discount measures.
Broader Safety Context
The disclosure of CVE-2025-13915 reinforces the persistent threat posed by authentication bypass vulnerabilities in enterprise platforms reminiscent of IBM API Join. Labeled underneath CWE-305 and CWE-287, the flaw demonstrates how implementation weaknesses can negate in any other case strong authentication controls. Regardless of the absence of confirmed exploitation, the vulnerability, distant assault floor, and demanding CVSS rating of 9.8 make fast remediation crucial.
The Cyber Safety Company of Singapore’s alert displays heightened regional scrutiny of high-impact vulnerabilities affecting extensively deployed enterprise software program. IBM’s advisory, first revealed on 17 December 2025 and bolstered in January 2026, gives clear steerage on patching and mitigation. Organizations operating affected variations of IBM API Join ought to assess publicity immediately and apply the really useful fixes to cut back threat.
Menace intelligence information from Cyble Imaginative and prescient additional confirms the vulnerability’s severity, its impression on confidentiality, integrity, and availability, and the effectiveness of upgrading as the first remediation.
