Exploitation evidence

Disclosed: evidence found.

Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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 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

This vulnerability is fixed in IceWarp versions 14.2.0.12 and 14.1.0.20. Users should upgrade to one of these versions or later to remediate the issue. No additional mitigation steps are required once the update is applied.

Description

This vulnerability allows remote attackers to disclose sensitive information on affected installations of IceWarp. Authentication is not required to exploit this vulnerability. The ZDI has assigned a CVSS rating of 7.5. The following CVEs are assigned: CVE-2026-2493.

Impact

Successful exploitation allows remote attackers to disclose sensitive information on affected IceWarp installations without requiring authentication. The attacker can access files with root privileges, potentially exposing highly sensitive data. There is no impact on integrity or availability reported.

Summary

The IceWarp collaboration platform contains a directory traversal information disclosure vulnerability (CVE-2026-2493) due to insufficient validation of a user-supplied 'ticket' parameter. This allows unauthenticated remote attackers to read sensitive files on affected systems with root context. The vulnerability has a CVSS v3 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high confidentiality impact without affecting integrity or availability. The issue was reported to IceWarp in December 2025 and publicly disclosed in February 2026. Official patches are available in IceWarp versions 14.2.0.12 and 14.1.0.20.
