CVE-2021-26787
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 cross site scripting (XSS) vulnerability in Genesys Workforce Management 8.5.214.20 can occur (during record deletion) via the Time-off parameter.
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 confidenceA stored cross-site scripting (XSS) vulnerability exists in Genesys Workforce Management version 8.5.214.20. The vulnerability is triggered via the Time-off parameter during record deletion operations, allowing an attacker to inject malicious JavaScript that executes when the deletion occurs or when the record is subsequently accessed.

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 installed Genesys Workforce Management versionAccess the system administration panel or check the application version through the Help > About menu in the Genesys WFM client. Alternatively, query the system using the administrative interface or check the installation directory for version metadata files.Affected if The installed version is exactly 8.5.214.20
-
Confirm Time-off management feature is enabledNavigate to the Genesys WFM configuration settings and verify whether the Time-off module or feature is activated for user access. Check user permissions to determine if the Time-off parameter configuration is accessible.Affected if The Time-off feature is enabled and accessible to users who can create or modify Time-off records
-
Verify deletion operations are permitted on Time-off recordsAccess the Time-off record management interface and attempt to locate the delete or remove function for existing Time-off entries. Check if the deletion workflow is available in the user role permissions.Affected if Deletion functionality for Time-off records is available and permitted for the user role in question
-
Inspect Time-off records for injected contentReview existing Time-off records in the database or through the administrative console. Examine the Time-off parameter fields for any unexpected or encoded content that may indicate prior exploitation or test payloads.Affected if Any Time-off records contain unsanitized user-supplied content in the Time-off parameter fields that could contain script tags or event handlers
The environment is affected if the installed Genesys WFM version is exactly 8.5.214.20 and the Time-off deletion feature is accessible, allowing stored XSS payloads in Time-off parameters to execute upon record deletion or access.

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 dataApply vendor-supplied patch for CVE-2021-26787. Until patch is available, implement input validation and output encoding on the Time-off parameter, and consider disabling deletion functionality for records containing user-supplied Time-off data as a compensating control.
