CVE-2026-11442
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAllegra exportReport Directory Traversal Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Allegra. Authentication is required to exploit this vulnerability. The specific flaw exists within the exportReport method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to disclose information in the context of the service account. Was ZDI-CAN-28208.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA directory traversal vulnerability exists in the exportReport method of Allegra. The method fails to properly validate user-supplied paths before using them in file operations, allowing authenticated attackers to use path traversal sequences (e.g., ../) to access sensitive files outside the intended directory. The vulnerability is exploitable remotely but requires valid authentication.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Allegra product installationLocate the Allegra application directory or executable and note the installed version by checking the application's about page, version file, or binary metadataAffected if The installed version falls within any vulnerable release range for Allegra
-
Verify exportReport method is accessibleIdentify whether the exportReport endpoint or function is exposed in the application. Check API documentation, web routes, or by enumerating available report export featuresAffected if The exportReport method is exposed and callable by authenticated users
-
Confirm user authentication is enabledReview authentication configuration to determine if the exportReport feature requires valid credentials, and check which user roles can access itAffected if The exportReport method can be invoked by any authenticated user without additional path validation controls
-
Test for path traversal vulnerabilityIf you have a test environment with an authenticated account, attempt to call exportReport with a path containing traversal sequences such as ../../../../etc/passwd or ../../windows/win.ini and observe if the application returns file contents outside the intended directoryAffected if The application returns content from files outside the designated export directory
-
Review input validation implementationInspect the source code or configuration of the exportReport method to determine whether path sanitization, canonicalization, or directory whitelisting is implemented before file operationsAffected if No path validation, canonicalization, or directory restriction is present in the exportReport implementation
You are affected if the Allegra exportReport method is accessible to authenticated users and lacks proper path validation to block directory traversal sequences
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement strict input validation on the path parameter in the exportReport method to prevent path traversal attacks. Validate that the supplied path resolves to an allowed directory and reject any path containing traversal sequences or absolute paths outside permitted boundaries.
