Exploitation evidence

Disclosed: evidence found.
CVE published 5 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed

No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 31 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

Red Hat has released Kiali version 1.73.26 which includes fixes for these vulnerabilities. Users should upgrade to this version to remediate the issues. Additionally, to mitigate the prototype pollution vulnerability, strict input validation should be implemented to block user input containing property paths such as __proto__, constructor, and prototype before passing them to _.unset and _.omit functions. Red Hat's advisory provides detailed guidance and documentation for the update. No further action is required once the update is applied.

Description

Red Hat OpenShift Service Mesh 2.6 includes Kiali 1.73.26, which addresses two security vulnerabilities: a denial of service caused by improper input validation in array parsing (CVE-2025-15284) and a prototype pollution vulnerability in Lodash's _.unset and _.omit functions (CVE-2025-13465). The prototype pollution flaw allows attackers controlling property paths to delete methods from global prototypes, resulting in denial of service. The vulnerabilities are rated with important severity due to their impact on availability. Red Hat has released Kiali 1.73.26 as a security update to mitigate these issues.

Impact

The vulnerabilities can cause denial of service by improper input validation and prototype pollution that deletes essential methods from global prototypes. This results in loss of functionality and availability degradation in the affected applications. The prototype pollution vulnerability does not allow overwriting behavior, limiting impact to denial of service only. There are no confidentiality or integrity impacts reported. The vulnerabilities affect the Kiali component used in Red Hat OpenShift Service Mesh 2.6. No known exploits in the wild have been reported.

CWE-1321Improperly Controlled Modification of Object Prototype Attributes (Prototype Pollution) (opens in a new tab)
Variant weakness
The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
Implementation
By freezing the object prototype first (for example, Object.freeze(Object.prototype)), modification of the prototype becomes impossible.
Architecture and Design
By blocking modifications of attributes that resolve to object prototype, such as proto or prototype, this weakness can be mitigated.
Implementation · Input Validation
When handling untrusted objects, validating using a schema can be used.

CWE-770Allocation of Resources Without Limits or Throttling (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #25
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
Requirements
Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
Architecture and Design
Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended.
