A cross-site scripting (XSS) vulnerability in the component /master/auth/OnedriveRedirect.php of PicUploader commit fcf82ea allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the error_description parameter.
Security readout for executives and security teams
Plain-English summary
CVE-2024-44794 is a reflected cross-site scripting issue in PicUploader's OneDrive redirect handler. If a user follows a crafted link, attacker-controlled script or HTML could run in that user's browser in the site's context.
Executive priority
Treat as a moderate web application risk. Prioritize if PicUploader is internet-facing, used by authenticated staff, or shares browser trust with sensitive applications. It is not currently supported by sources as actively exploited.
Technical view
The CVE describes CWE-79 in /master/auth/OnedriveRedirect.php in PicUploader commit fcf82ea. The error_description parameter can carry crafted content that is rendered as web script or HTML. CVSS 3.1 is 6.1, with network access, low complexity, no privileges, and user interaction required.
Likely exposure
Exposure appears limited to PicUploader deployments containing the referenced OneDrive redirect component, especially code at or derived from commit fcf82ea. The CVE record lists affected vendor, product, versions, and CPEs as n/a, so asset matching may require source review.
Exploitation context
The source bundle does not show CISA KEV listing or confirmed active exploitation. Successful abuse requires user interaction, such as opening a crafted redirect URL, and could affect confidentiality and integrity in the browser session.
Researcher notes
Evidence is narrow: public CVE metadata and a GitHub issue identify the vulnerable component and parameter, but affected version ranges, fix commit, and exploit activity are not established in the provided bundle.
Mitigation direction
Check the PicUploader repository and issue 91 for official guidance or a maintained fix.
Update away from the vulnerable commit if a trusted fixed version is available.
Review the OneDrive redirect handler before exposing it to internet users.
Apply defensive output encoding and validation if maintaining a local fork.
Consider disabling the affected OneDrive redirect path until reviewed.
Validation and detection
Inventory PicUploader deployments and identify whether commit fcf82ea or the vulnerable component is present.
Review /master/auth/OnedriveRedirect.php for unescaped use of error_description.
Check whether the OneDrive redirect path is reachable from untrusted networks.
Review web logs for suspicious requests containing error_description on that endpoint.

Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
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.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
