Drupal avatar_uploader 7.x-1.0-beta8 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject malicious scripts by manipulating the file parameter. Attackers can craft URLs with script payloads in the file parameter of avatar_uploader.pages.inc to execute arbitrary JavaScript in victim browsers.
Security readout for executives and security teams
Plain-English summary
This is a reflected XSS issue in the Drupal avatar_uploader module version 7.x-1.0-beta8. An attacker could trick a user into opening a crafted link that runs JavaScript in that user’s browser. The evidence does not show active exploitation or server compromise.
Executive priority
Treat as a medium-priority web application risk. It is not evidenced as actively exploited, but public exploit material raises urgency for any internet-facing Drupal site using the vulnerable module.
Technical view
CVE-2022-50957 is CWE-79 reflected XSS in avatar_uploader.pages.inc. The file parameter can reflect attacker-controlled script content. CVSS 3.1 is 6.1 because exploitation is network-reachable, low complexity, unauthenticated, and requires user interaction with changed scope.
Likely exposure
Exposure is likely limited to Drupal sites that installed avatar_uploader 7.x-1.0-beta8 and expose the affected module route to users or visitors.
Exploitation context
A public ExploitDB reference exists, but the supplied evidence does not show KEV listing or active exploitation. Attack success requires a victim to open a crafted URL. Impact is browser-side data exposure or action manipulation within the affected Drupal session context.
Researcher notes
Do not broaden scope beyond avatar_uploader 7.x-1.0-beta8 based on the supplied evidence. Patch status is not confirmed in the bundle, so validation should focus on version presence, route exposure, and vendor guidance.
Mitigation direction
Inventory Drupal sites for avatar_uploader 7.x-1.0-beta8.
Disable or remove avatar_uploader if it is not required.
Check Drupal project guidance for a fixed release or supported replacement.
Review WAF rules for suspicious avatar_uploader file parameter requests.
Warn users not to trust unexpected links to affected Drupal sites.
Validation and detection
Confirm whether avatar_uploader is installed and identify its exact version.
Review public routes exposing avatar_uploader.pages.inc behavior.
Check access logs for unusual file parameter patterns.
Verify remediation by confirming the vulnerable version is absent or disabled.
Document whether any compensating controls are temporary or permanent.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
