Exploitation evidence

Disclosed: evidence found.

Detectable: no evidence on record.
No public nuclei template indexed

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.

What to do

AI-suggested

Until a patch is available, consider restricting network access to the affected service or disabling it if feasible to prevent exploitation.

Description

This vulnerability allows remote attackers to execute arbitrary code on affected installations of claude-hovercraft. Authentication is not required to exploit this vulnerability. The ZDI has assigned a CVSS rating of 9.8. The following CVEs are assigned: CVE-2025-15060.

Impact

Successful exploitation allows remote attackers to execute arbitrary code on affected installations without authentication. This can lead to full compromise of the affected system under the service account's privileges, impacting confidentiality, integrity, and availability. The vulnerability is rated critical with a CVSS score of 9.8. No known exploits in the wild have been reported at the time of disclosure.

Summary

The vulnerability in claude-hovercraft arises from the executeClaudeCode method's failure to properly validate a user-supplied string prior to executing it as a system call. This lack of input validation enables remote attackers to perform command injection, leading to arbitrary code execution with the privileges of the service account running the application. Authentication is not required to exploit this issue, making it highly critical. The Zero Day Initiative assigned a CVSS score of 9.8, reflecting the high impact and ease of exploitation.
