Security readout for executives and security teams
Plain-English summary
CVE-2026-30457 is a critical code-execution issue reported in FuelCMS v1.5.2’s Dwoo parser component. A remote unauthenticated attacker could potentially run arbitrary PHP code, which can lead to full site compromise. The source bundle does not name a fixed version.
Executive priority
Treat this as urgent for any exposed FuelCMS v1.5.2 site. The risk is potential remote full compromise, while fix information is incomplete. Reduce exposure immediately and assign owners to confirm vendor remediation.
Technical view
The CVE describes CWE-94 improper code generation/control in /parser/dwoo for Daylight Studio FuelCMS v1.5.2. CVSS 3.1 is 9.8, with network access, low complexity, no privileges, and no user interaction required, impacting confidentiality, integrity, and availability.
Likely exposure
Primary exposure is FuelCMS v1.5.2 deployments using or shipping the Dwoo parser component, especially internet-facing systems. The official affected-product metadata is incomplete, so teams should validate by application version and component path rather than relying only on CPE matching.
Exploitation context
The provided bundle does not show CISA KEV listing or confirmed active exploitation. A public Pentest-Tools advisory PDF is cited, so technical details may be publicly available, but the bundle does not prove in-the-wild exploitation.
Researcher notes
Do not rely on the CVE affected array because it lists vendor and product as n/a. The description names FuelCMS v1.5.2 and /parser/dwoo. Confirm behavior against legitimate test assets only, and avoid publishing exploit procedure details.
Mitigation direction
- Check Daylight Studio/FUEL CMS guidance for patched versions before applying changes.
- Restrict public access to FuelCMS administration and parser-related functionality where possible.
- If unused, disable or remove Dwoo parser functionality after compatibility review.
- Prioritize upgrade, isolation, or replacement for internet-facing FuelCMS v1.5.2 systems.
- Increase monitoring for suspicious PHP execution, file changes, and web process anomalies.
Validation and detection
- Inventory all FuelCMS instances and confirm exact version numbers.
- Check whether /fuel/modules/fuel/libraries/parser/dwoo exists in deployed code.
- Identify whether affected systems are internet-facing or reachable by untrusted users.
- Review web and application logs for unusual parser errors or PHP execution indicators.
- Track the CVE record and vendor repository for fix or mitigation updates.

Improper Control of Generation of Code ('Code Injection')
Improper Control of Generation of Code ('Code Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
