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 5 Nov 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

Upgrade Apache OFBiz to 24.09.08.

Description

CVE-2026-74841 is an uncontrolled resource consumption vulnerability in Apache OFBiz affecting versions prior to 24.09.08. In multitenant deployments, the application builds a per-tenant delegator name from a user-supplied tenant ID before verifying tenant existence. The internal cache retains all delegator names requested, including invalid ones, allowing an unauthenticated attacker to submit arbitrary tenant IDs and cause unbounded cache growth, leading to increased memory and database load.

Impact

An unauthenticated attacker can cause excessive memory and database resource consumption by submitting arbitrary tenant IDs, potentially leading to denial of service or degraded performance in multitenant deployments of Apache OFBiz prior to version 24.09.08.

Summary

This vulnerability arises because ContextFilter and LoginWorker components in Apache OFBiz construct delegator names from a request-supplied userTenantId parameter without confirming tenant existence first. DelegatorFactory caches every delegator name it attempts to resolve, even those that fail. An attacker can exploit this by sending a continuous stream of arbitrary tenant IDs, causing the cache to grow indefinitely. This results in uncontrolled resource consumption, specifically memory and database load, which can degrade service availability or performance. The issue is fixed in version 24.09.08.

CWE-400Uncontrolled Resource Consumption (opens in a new tab)
Class weaknessLikelihood of exploit: High
The product does not properly control the allocation and maintenance of a limited resource.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
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. A strong authentication and access control model will help prevent such attacks from occurring in the first place.
Architecture and Design
Mitigation of resource exhaustion attacks requires that the target system either: recognizes the attack and denies that user further access for a given amount of time, or; uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Architecture and Design
Ensure that protocols have specific limits of scale placed on them.

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.
