CVE-2026-8737
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 weakness has been identified in Sanluan PublicCMS 5.202506.d. This issue affects the function execute of the file publiccms-trade/src/main/java/com/publiccms/views/directive/trade/TradeAddressListDirective.java of the component Trade Address Query Handler. Executing a manipulation of the argument userId/id can lead to missing authentication. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceSanluan PublicCMS 5.202506.d contains an authentication bypass vulnerability in the TradeAddressListDirective component. The execute function in TradeAddressListDirective.java fails to properly validate authentication when processing the userId/id argument, allowing unauthenticated remote attackers to query trade address information by manipulating these arguments.

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 PublicCMS installation and versionLocate the PublicCMS installation directory and check the version file or WAR metadata. Common locations: webapps/ROOT/WEB-INF/classes/version.properties or the main JAR manifest.Affected if The installed version matches 5.202506.d or falls within the affected version range.
-
Verify TradeAddressListDirective component existsLocate TradeAddressListDirective.java in the compiled classes or source. Search for the file in the application's classpath under the directives package.Affected if The TradeAddressListDirective.class file exists in the deployed application.
-
Inspect execute method for authentication validationDecompile or inspect TradeAddressListDirective.class and examine the execute method. Look for authentication checks before processing userId or id parameters.Affected if The execute method lacks proper authentication enforcement when handling userId/id arguments.
-
Check if trade address endpoint is exposed without authAttempt to access the trade address list endpoint using the directive with a manipulated userId parameter, observing whether the request succeeds without providing valid authentication tokens.Affected if The application returns trade address data without requiring valid authentication.
A user is affected if running PublicCMS version 5.202506.d with TradeAddressListDirective accessible and lacking authentication validation in its execute method, allowing unauthenticated trade address queries.

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 proper authentication enforcement in the TradeAddressListDirective execute method to verify user identity before processing userId/id parameters, and ensure all trade address queries require valid authentication tokens or session context.
