CVE-2025-36187 is a medium-severity vulnerability affecting IBM Knowledge Catalog versions 5.0.0 through 5.2.1. This vulnerability allows local privileged users to access potentially sensitive information stored in log files. The CVSS score for this vulnerability is 4.4, indicating a medium level of risk that organizations should not overlook.
Organizations must understand that the exposure of sensitive information can have serious implications, especially in environments where confidentiality is paramount. Attackers may leverage this vulnerability to gain insights into the system, potentially leading to further exploits.
The urgency for defenders is moderate. Organizations should address this vulnerability in their priority patch cycle to reduce the risk of sensitive data exposure. Proper remediation ensures that sensitive information is not easily accessible to unauthorized users.
Currently, there are no known exploits or public proofs of concept for this vulnerability, but the nature of the issue warrants immediate attention. Organizations should prioritize patching immediately.
Vulnerability Details
The official CVE description states that IBM Knowledge Catalog Standard Cartridge versions 5.0.0 to 5.2.1 store potentially sensitive information in log files that could be read by a local privileged user. The vulnerability is classified under CWE-532, which pertains to the exposure of sensitive information through log files.
The CVSS 3.1 score is 4.4, with an attack vector of local, attack complexity of low, and high privileges required. This suggests that an attacker would need to have some level of access to the system, but once inside, exploitation could be straightforward.
The affected products include the IBM Knowledge Catalog across several versions, indicating a widespread impact on installations that have not yet been patched. The vulnerability was published on March 25, 2026.
Technical Analysis
The root cause of CVE-2025-36187 is linked to inadequate handling of sensitive information within log files. The attack vector is local, meaning an attacker must have access to the system to exploit this vulnerability. The attack complexity is low, indicating that once access is gained, exploiting this vulnerability is straightforward.
The required privileges for exploitation are high, meaning attackers would need to be local privileged users. User interaction is not required, adding to the risk as this can be done without any additional steps from the user.
In terms of impact, this vulnerability has a high confidentiality impact since sensitive information may be accessed. However, there is no integrity or availability impact associated with this vulnerability, limiting the potential damage to data exposure.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-36187 is significant, particularly in organizations that manage sensitive data. The vulnerability impacts multiple versions of IBM Knowledge Catalog, making it critical for organizations to assess their exposure.
Risk to organizations includes the potential unauthorized access to sensitive information, which could lead to data breaches or compliance issues. The blast radius is considerable as it affects various versions of the product, meaning many organizations may be at risk.
Given the CVSS score of 4.4, organizations should schedule remediation to address this vulnerability. Although it is not classified as critical, the potential for sensitive data exposure necessitates action to mitigate risks.
