Security readout for executives and security teams
Plain-English summary
CVE-2026-1445 is an unrestricted file upload issue in iJason-Liu Books_Manager. A remote authenticated user may be able to upload unintended file types through the book cover upload feature, potentially affecting confidentiality, integrity, and availability. Public exploit material is reported, but CISA KEV does not list active exploitation.
Executive priority
Treat as a moderate, near-term remediation item if Books_Manager is used, especially on internet-facing systems. Public exploit availability increases operational risk, but available evidence indicates authenticated access is required and no active exploitation is confirmed.
Technical view
The issue affects controllers/books_center/upload_bookCover.php in Books_Manager up to commit 298ba736387ca37810466349af13a0fdf828e99c. Manipulation of the book_cover argument can lead to unrestricted upload. VulDB maps this to CWE-434 and CWE-284 with CVSS 2.0 score 5.8, AV:N/AC:L/Au:M/C:P/I:P/A:P.
Likely exposure
Exposure is likely limited to organizations running iJason-Liu Books_Manager with authenticated access to the book cover upload workflow. Internet-facing deployments raise risk. Specific affected or fixed versions are not available because the project reportedly uses a rolling release model.
Exploitation context
The source bundle states the attack can be initiated remotely and that public exploit material exists. Authentication is required according to the CVSS vector. There is no KEV listing and no cited evidence of active exploitation in the wild.
Researcher notes
Evidence is mostly from VulDB/CVE metadata. The precise fixed release is not named, and versioning is unclear due to rolling releases. Avoid assuming affected versions beyond the cited commit. Validate exposure through code review and deployment inventory rather than scanner version matching alone.
Mitigation direction
- Identify any deployments of iJason-Liu Books_Manager.
- Restrict access to the Books_Manager administrative or upload functions.
- Review vendor/project guidance for updated code or commits.
- Limit accepted upload types and storage execution where configurable.
- Monitor upload directories and web logs for suspicious files.
Validation and detection
- Confirm whether Books_Manager is deployed and exposed to untrusted users.
- Check deployed code against commit 298ba736387ca37810466349af13a0fdf828e99c.
- Review upload_bookCover.php handling of the book_cover parameter.
- Verify whether upload paths prevent execution of uploaded content.
- Look for unusual recent uploads in book cover storage locations.
