Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

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 30 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.

AI-suggested

Until a fix is available, restrict or monitor access to cache query submission to trusted users with BULK_READ permission to reduce risk. No vendor advisory states that no action is required or that the issue is already mitigated.

Description

CVE-2026-119542 is a vulnerability in the Ickle query parser component of Infinispan used in the Red Hat build of Apache Camel 4 for Quarkus 3. It allows an authenticated user with BULK_READ permission to submit a cache query with deeply nested predicates that cause uncontrolled recursion, leading to a StackOverflowError and potential denial of service due to thread stack exhaustion.

Impact

The impact is limited to availability, where a crafted query with deeply nested predicates can cause a StackOverflowError, potentially leading to denial of service of the affected service. There is no impact on confidentiality or integrity. Exploitation requires authenticated access with BULK_READ permission.

Summary

This vulnerability arises from uncontrolled recursion in the Ickle query parser of Infinispan. When a query contains deeply nested predicates, the recursive parsing can exhaust the Java thread stack, causing an uncaught StackOverflowError. An attacker with authenticated access and BULK_READ permission who can submit cache queries may trigger this condition, impacting availability. The CVSS v3.1 base score assigned by Red Hat is 4.3 (medium severity), reflecting a network attack vector with low complexity and low privileges required, no user interaction, unchanged scope, and only availability impact. No public exploit or known exploitation in the wild has been reported. The vendor advisory does not explicitly confirm a patch or fixed versions at this time.
