bunkerweb is an Open-source and next-generation Web Application Firewall (WAF). From 1.6.2 until 1.6.12, the BunkerWeb web UI BiscuitMiddleware authorization bypass list included the /cache/ URL prefix, so routes in src/ui/app/routes/cache.py protected only by @login_required, including POST /cache/delete, allowed low-privilege read-only reader accounts to permanently delete job cache files containing blacklist, greylist, DNSBL, CrowdSec, GeoIP, ModSecurity CRS, Let's Encrypt, ACME, and custom configuration data. This issue is fixed in version 1.6.12.
CVE-2026-61718
This medium-severity CVE scores 5.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 77% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
