Detectable: no evidence on record.

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 2026-10-26.

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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC 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

Red Hat has released updated VolSync container images as part of the v0.9.2 release that include the security fix for CVE-2024-24786. Users should update to the latest VolSync v0.9.2 images provided by Red Hat to remediate this issue. No additional mitigation steps are indicated in the advisory. Patch status is confirmed as fixed in the updated container images.

Description

VolSync v0.9.2 is a Kubernetes operator that enables asynchronous replication of persistent volumes within a cluster, or across clusters. After deploying the VolSync operator, you can create and maintain copies of your persistent data. For more information about VolSync, see: https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.10/html/business_continuity/business-cont-overview#volsync or the VolSync open source community website at: https://volsync.readthedocs.io/en/stable/. This advisory contains enhancements and updates to the VolSync container images. Security fix(es): * CVE-2024-24786 - golang-protobuf: encoding/protojson, internal/encoding/json: infinite loop in protojson.Unmarshal when unmarshaling certain forms of invalid JSON

Impact

An infinite loop vulnerability in the protojson.Unmarshal function can cause the VolSync operator to hang or become unresponsive when processing certain invalid JSON data. This may disrupt asynchronous replication of persistent volumes managed by VolSync, potentially impacting data availability or replication consistency within Kubernetes clusters. The vulnerability is rated moderate by Red Hat Product Security.

Summary

The Red Hat security advisory RHSA-2024:4144 addresses a moderate severity vulnerability (CVE-2024-24786) in VolSync v0.9.2 for RHEL 9. The issue involves an infinite loop in the golang-protobuf encoding/protojson package's internal JSON unmarshaling logic when handling specific malformed JSON inputs. This could cause the VolSync operator to hang or become unresponsive during processing. The advisory updates the VolSync container images to include the fix. VolSync is a Kubernetes operator that facilitates asynchronous replication of persistent volumes within or across clusters. The advisory does not specify exact affected versions but relates to the v0.9.2 release images.

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.
