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 26 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.
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 DevWorkspace Operator version 0.39.0 which addresses this vulnerability. Users should upgrade to version 0.39.0 or later. No other mitigations meeting Red Hat's standards are currently available. Until upgraded, systems remain vulnerable to denial of service via malicious SSH agent messages.

Description

The DevWorkspace Operator extends OpenShift to provide DevWorkspace support.

Impact

The vulnerability causes the SSH agent client process to crash when receiving an unexpected message type, resulting in a denial of service. This can disrupt developer tooling and automation that rely on SSH agent interactions, especially in environments with forwarded SSH agents or shared workspaces. There is no impact on confidentiality or integrity, but availability is significantly affected.

Summary

CVE-2025-47913 is a flaw in the golang.org/x/crypto/ssh/agent package used by the DevWorkspace Operator that causes the SSH agent client to panic when a peer responds with a generic SSH_AGENT_SUCCESS (0x06) message to requests expecting typed replies. The unmarshalling logic does not handle this unexpected but protocol-legal message type gracefully, resulting in a panic or nil-pointer dereference. This vulnerability allows a malicious or misbehaving SSH agent to reliably crash the client process, causing a denial of service. It is particularly impactful in environments using SSH agent forwarding, shared workspaces, or CI/CD runners. The issue is a design-level reliability flaw rather than a simple error-handling bug. Red Hat has released DevWorkspace Operator version 0.39.0 to address this issue.

CWE-1050Excessive Platform Resource Consumption within a Loop (opens in a new tab)
Base weakness
The product has a loop body or loop condition that contains a control element that directly or indirectly consumes platform resources, e.g. messaging, sessions, locks, or file descriptors.
OWASP Cheat Sheets
File Upload (opens in a new tab)
OWASP ASVS 4.0.3
V12.1.1 (opens in a new tab)
From MITRE CWE, MITRE CAPEC and OWASP (Top 10, OpenCRE).
CWE-241Improper Handling of Unexpected Data Type (opens in a new tab)
Base weakness
The product does not handle or incorrectly handles when a particular element is not the expected type, e.g. it expects a digit (0-9) but is provided with a letter (A-Z).
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Implementation · Input Validation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174).
