CVE-2026-2737
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 · uneditedA vulnerability exists in Progress Flowmon versions prior to 12.5.8 and 13.0.6, whereby an administrator who clicks a malicious link provided by an attacker may inadvertently trigger unintended actions within their authenticated web session.
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 · moderate confidenceThis is a Cross-Site Request Forgery (CSRF) vulnerability in the Progress Flowmon web interface. An authenticated administrator who clicks a malicious link crafted by an attacker can have unintended actions executed within their authenticated session, potentially allowing the attacker to perform administrative actions via the victim's session.

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.
-
Identify the installed Flowmon versionAccess the Flowmon administrative interface and navigate to the System Information or About page, typically found under Administration > System > Information or a similar path. Alternatively, check the version via the CLI if available using 'flowmon -v' or by examining installed package information.Affected if The installed version falls within the ranges >= 12.0.0 and < 12.5.8, or >= 13.0.0 and < 13.0.6.
-
Confirm web interface accessibilityVerify that the Flowmon web interface is accessible on the network. Attempt to reach the login page at the standard Flowmon URL (typically https://<hostname>/ or the configured web interface port).Affected if The web interface is exposed and reachable over HTTP/HTTPS.
-
Verify administrative session stateLog into the Flowmon web interface as an administrator and inspect the browser's developer tools (Network tab) when performing administrative actions such as creating a user, modifying system settings, or changing configurations.Affected if Administrative actions can be performed without triggering CSRF token validation in the requests.
-
Check for CSRF token presence in admin actionsSubmit an administrative request (such as a settings change) and examine the HTTP request headers and body. Look for a CSRF token parameter or header (commonly named 'csrf_token', 'token', or 'X-CSRF-Token') in the request.Affected if Administrative HTTP requests lack CSRF protection tokens or do not validate them.
You are affected if your Flowmon version is between 12.0.0 and 12.5.7 inclusive, or between 13.0.0 and 13.0.5 inclusive, and the web interface is accessible to potential attackers who could craft malicious links for authenticated administrators to click.

dbcve · scoped12.5.813.0.6
Update Flowmon to version 12.5.8 or 13.0.6 or later to obtain the vendor patch. Additionally, administrators should avoid clicking untrusted links while authenticated.
Flowmon 12.5.8 or 13.0.6 (depending on current major version)
- Back up the current Flowmon configuration and any critical data
- Determine your current Flowmon major version (12.x or 13.x)
- Download Flowmon version 12.5.8 (if currently on 12.x branch) or version 13.0.6 (if currently on 13.x branch) from the official Progress Flowmon download repository
- Install the downloaded upgrade following the standard Flowmon upgrade procedure
- After upgrade, verify the web interface is accessible and functioning normally
- Confirm the administrator account can log in successfully
