CVE-2026-100501
MediumCVSS 6.5Summary
Flame through 2.4.0 contains an improper restriction of excessive authentication attempts vulnerability in the POST /api/auth login endpoint that allows unauthenticated attackers to brute-force the admin password. Attackers can submit unlimited password guesses without rate limiting, attempt counters, lockouts, or delays to gain full administrator access and modify application configuration.
Risk Assessment
The risk includes administrator account takeover via brute-force attack, potentially leading to full control over the application and its configuration.
Recommendation
It is recommended to upgrade Flame to a patched version that introduces login attempt restrictions such as rate limiting and account lockouts.
Other vulnerabilities in Flame
See all- CVE-2026-100502Medium
Flame through 2.4.0 contains an insufficient session expiration vulnerability in the login endpoint that allows attackers with former admin access to obtain tokens with arbitrary lifespans by supplying unvalidated duration parameters. Attackers can mint near-permanent administrator tokens that survive password changes, retaining full control of the dashboard since tokens are verified only against a static JWT secret that is never rotated.
- CVE-2026-100418Medium
Flame through 2.4.0 contains an information exposure vulnerability in the unauthenticated GET /api/config endpoint that returns the entire configuration object without field redaction. Attackers can retrieve the stored weather API key and internal operational settings by sending a single unauthenticated request to consume provider quota or access sensitive configuration data.
