Security readout for executives and security teams
Plain-English summary
This is a low-severity Fortinet issue where a crafted link could let an attacker add unexpected HTTP response headers, but only when they possess a valid web filter override token and a user clicks the link.
Executive priority
Handle through normal patch governance unless the affected feature is heavily used or externally exposed workflows depend on override links. The business risk is limited integrity impact, not system compromise, based on current sources.
Technical view
CVE-2025-62675 is CWE-113 HTTP response splitting in FortiOS and FortiProxy web filter override handling. The CVSS 3.1 score is 3.4 with network reachability, high complexity, user interaction required, and limited integrity impact only.
Likely exposure
Exposure is most relevant where affected FortiOS or FortiProxy versions use web filter override tokens. The provided description names FortiOS 7.6.0-7.6.4, all 7.4 and 7.2, and equivalent FortiProxy branches. Exact branch status should be verified against Fortinet's advisory.
Exploitation context
Provided sources do not report active exploitation. Exploitation requires a valid web filter override token and convincing a user to click a crafted link, making broad automated exploitation less likely from the available evidence.
Researcher notes
The source bundle contains broad CPE entries, including FortiPAM and older branches, while the narrative description specifically names FortiOS and FortiProxy affected ranges. Treat Fortinet PSIRT as authoritative for exact applicability and remediation.
Mitigation direction
- Review Fortinet advisory FG-IR-26-152 for fixed releases or supported workarounds.
- Upgrade affected FortiOS and FortiProxy systems according to Fortinet guidance.
- Limit and monitor web filter override token issuance and use.
- Educate administrators and users not to follow unexpected override links.
Validation and detection
- Inventory FortiOS and FortiProxy versions against Fortinet advisory FG-IR-26-152.
- Confirm whether web filter override functionality is enabled or used.
- Review logs for unusual web filter override token activity.
- Check whether compensating controls inspect suspicious redirected or crafted links.

Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting')
Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
