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

Upgrade CallBackery (Perl module) to 0.60.1.

AI-suggested

Upgrade CallBackery to version 0.60.1 or later, where this path traversal vulnerability is fixed. No other mitigation is necessary as the fix addresses the root cause.

Description

CallBackery versions before 0.60.1 for Perl contain a path traversal vulnerability in the /doc route that allows unauthenticated clients to read arbitrary files accessible to the server process. This occurs because the documentation plugin mounted at /doc passes user input to Pod::Simple::Search->find without validation, enabling traversal outside the intended directory. The vulnerability is fixed in version 0.60.1.

Impact

Unauthenticated attackers can read arbitrary files on the server that the CallBackery process has permission to access. This can lead to disclosure of sensitive information. The vulnerability is limited to file reading via the documentation route and does not require authentication.

Summary

CallBackery before version 0.60.1 has a path traversal vulnerability (CWE-22) in its documentation plugin mounted at /doc. The route does not validate the requested document name, which is passed to Pod::Simple::Search->find. This function splits the name on '::' and joins the parts into a file path, allowing traversal outside the intended directories (e.g., '..::..::..::etc::motd'). As a result, any file readable by the server process can be accessed by unauthenticated clients, with the content rendered as POD if applicable. The issue is resolved in version 0.60.1.

Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #6OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
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.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
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).
