Potential Security Information Disclosure in Team Grid
HIGH P8
Prompt to Fix
The issue is that team member personal information is potentially exposed without access controls. Fix it by implementing proper authentication checks and role-based authorization before displaying team member details, and verify API endpoints require valid authentication tokens.
Why it's a bug
The team member grid displays what appears to be individual profile images with names/identifiers visible in a public-facing layout. Without proper access controls or authentication indicators, this could constitute an information disclosure vulnerability if this page is accessible to unauthorized users or if the team member data should not be publicly displayed.
Why it might not be a bug
This could be intentional design for a public team directory. If the website is meant to showcase team members publicly, this would be expected functionality rather than a security issue.
Suggested Fix
Verify that the team member grid and associated profile information requires proper authentication and authorization. Implement role-based access controls to ensure only authorized users can view team member details. Add security headers and implement CSRF protection if this is a sensitive section.
Why Fix
Preventing unauthorized access to employee/team member information protects privacy and reduces attack surface for social engineering and targeted attacks.

Extremely low contrast text throughout the gallery grid
CRIT P9
Prompt to Fix
The issue is that text labels in the gallery grid have insufficient contrast against the dark background, violating WCAG accessibility standards. Fix it by increasing text contrast to at least 4.5:1 using lighter text colors or adding background containers behind text labels.
Why it's a bug
The text labels in the gallery grid items are extremely faint and difficult to read against the dark teal background. This violates WCAG 2.1 AA standards for color contrast (minimum 4.5:1 for normal text). Users with low vision or color blindness would struggle to read the content.
Why it might not be a bug
The design aesthetic may intentionally use subtle text, but accessibility requirements supersede design preferences.
Suggested Fix
Increase the contrast of text labels by using white or light-colored text, or add a semi-transparent dark background behind text to ensure minimum 4.5:1 contrast ratio against the background.
Why Fix
Ensures the website is accessible to users with visual impairments and complies with WCAG 2.1 accessibility standards, which may be legally required.

Large black horizontal section with no visible content
HIGH P7
Prompt to Fix
The issue is a large empty black horizontal section occupying significant page space with no visible content or purpose. Fix it by either adding meaningful content, replacing it with a styled divider with appropriate spacing, or removing it entirely if it serves no design function.
Why it's a bug
There is a prominent black horizontal band/section taking up significant vertical space in the middle of the page with no discernible content, purpose, or visual hierarchy. This appears to be either a missing image, improperly styled divider, or layout error that disrupts the visual flow and user experience.
Why it might not be a bug
This could be an intentional design choice for visual separation, though the lack of any content or clear purpose makes it appear unintentional.
Suggested Fix
Either add meaningful content to this section, replace with a properly styled divider with appropriate spacing, or remove it entirely if it serves no purpose.
Why Fix
Large empty sections create confusion and reduce user engagement. Users may think content is loading or missing entirely, degrading the overall user experience.
