Security readout for executives and security teams
Plain-English summary
CVE-2025-45314 is a medium-severity cross-site scripting issue in hortusfox-web v4.4. An attacker could cause JavaScript to run in a victim’s browser through the /Calendar add function. This can expose user data or alter page behavior, but it requires user interaction and does not directly compromise the server.
Executive priority
Treat as a moderate-priority web application issue. Prioritize if hortusfox-web v4.4 is internet-facing or supports sensitive workflows. There is no provided evidence of active exploitation, but XSS can affect user trust and session integrity, so remediation tracking is warranted.
Technical view
The CVE describes CWE-79 XSS in the /Calendar endpoint of hortusfox-web v4.4, where crafted input to the add function can execute arbitrary JavaScript in a user browser context. CVSS 3.1 is 6.1: network-accessible, low complexity, no privileges required, user interaction required, changed scope, low confidentiality and integrity impact, no availability impact.
Likely exposure
Organizations running hortusfox-web v4.4 are the stated exposure group. Risk is higher where the application is internet-accessible or used by multiple authenticated users. The CVE record’s affected product metadata is incomplete, so confirm deployments by application name and version rather than CPE matching.
Exploitation context
Sources do not report active exploitation, and the CVE is not listed as KEV in the provided bundle. Exploitation requires a victim to interact with affected application content. Successful XSS could support session abuse, phishing within the application, or unauthorized actions within the victim’s permissions.
Researcher notes
The public record provides core vulnerability details but limited affected-product metadata and no named fix. The GitHub proof-of-concept reference may contain technical details; handle carefully and avoid testing against systems without authorization. Further analysis should confirm whether later hortusfox-web versions address the issue.
Mitigation direction
- Identify any hortusfox-web v4.4 deployments, especially internet-facing instances.
- Check the hortusfox-web repository and maintainer guidance for a fixed release or workaround.
- Apply vendor-provided updates or mitigations when available.
- Limit application exposure to trusted networks where feasible.
- Review input handling and output encoding around Calendar add functionality.
Validation and detection
- Inventory hortusfox-web instances and record deployed versions.
- Confirm whether /Calendar add functionality is enabled and reachable.
- Review application logs for suspicious Calendar entries or unusual user-driven script behavior.
- Use safe XSS testing in a controlled environment only with authorization.
- Monitor vendor repository and CVE record for updated remediation details.

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.
