Exploitation evidence

Disclosed: evidence found.
Public on cve.org; its publication date is not in this record
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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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

Allegra has issued an official update that corrects this vulnerability. Users should apply the update from Allegra's release notes at https://alltena.com/en/resources/release-notes/release-notes-for-release-9-0-0/ to remediate this issue.

Description

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Allegra. Authentication is required to exploit this vulnerability. The ZDI has assigned a CVSS rating of 6.5. The following CVEs are assigned: CVE-2026-11442.

Impact

Successful exploitation allows an authenticated remote attacker to disclose sensitive information by accessing files outside the intended directory scope. The information is exposed with the privileges of the service account running Allegra, potentially leading to data leakage.

Summary

This vulnerability in Allegra's exportReport method permits remote attackers with authentication to perform directory traversal attacks due to improper validation of user-supplied paths. Exploitation can lead to disclosure of sensitive information accessible by the service account. The vulnerability has a CVSS score of 6.5 (medium severity) and has been publicly disclosed with an official patch available from Allegra.
