  "details": "# Security Disclosure: SSRF via MetaIssuer Regex Bypass\n\n## Summary\n\nFulcio\u0027s `metaRegex()` function uses unanchored regex, allowing attackers to bypass MetaIssuer URL validation and trigger SSRF to arbitrary internal services.\n\nSince the SSRF only can trigger GET requests, the request cannot mutate state. The response from the GET request is not returned to the caller so data exfiltration is not possible. A malicious actor could attempt to probe an internal network through [Blind SSRF](https://portswigger.net/web-security/ssrf/blind).\n\n## Impact\n\n- SSRF to cloud metadata (169.254.169.254)\n- SSRF to internal Kubernetes APIs\n- SSRF to any service accessible from Fulcio\u0027s network\n- Affects ALL deployments using MetaIssuers\n\n## Patches\n\nUpgrade to v1.8.5.\n\n## Workarounds\n\nNone. If anchors are included in the meta issuer configuration URL, they will be escaped before the regular expression is compiled, not making this a sufficient mitigation. Deployments must upgrade to the latest Fulcio release v1.8.5.\n\n## Affected Code\n\n**File**: `pkg/config/config.go`  \n**Function**: `metaRegex()` (lines 143-156)\n\n```go\nfunc metaRegex(issuer string) (*regexp.Regexp, error) {\n    quoted := regexp.QuoteMeta(issuer)\n    replaced := strings.ReplaceAll(quoted, regexp.QuoteMeta(\"*\"), \"[-_a-zA-Z0-9]+\")\n    return regexp.Compile(replaced)  // Missing ^ and $ anchors\n}\n```\n\n## The Bug\n\nThe regex has no `^` (start) or `$` (end) anchors. Go\u0027s `regexp.MatchString()` does substring matching, so:\n\n```\nPattern:  https://oidc.eks.*.amazonaws.com/id/*\nRegex:    https://oidc\\.eks\\.[-_a-zA-Z0-9]+\\.amazonaws\\.com/id/[-_a-zA-Z0-9]+\n\nInput:    https://attacker.com/x/https://oidc.eks.foo.amazonaws.com/id/bar\nResult:   MATCHES (substring found)\n```\n\n## Exploit\n\n1. Attacker sends JWT with `iss` claim: `https://attacker.com/path/https://oidc.eks.x.amazonaws.com/id/y`\n2. Fulcio\u0027s `GetIssuer()` matches this against MetaIssuer patterns\n3. Unanchored regex matches the embedded pattern as substring\n4. Fulcio calls `oidc.NewProvider()` with attacker\u0027s URL\n5. HTTP request goes to `attacker.com`, not `amazonaws.com`\n6. Attacker returns OIDC discovery with `jwks_uri` pointing to internal service\n7. Fulcio fetches from internal service \u2192 SSRF",
