  "details": "### Impact \n\nA vulnerability was discovered in `go-git` whereby data integrity values for `.pack` and `.idx` files were not properly verified. This resulted in `go-git` potentially consuming corrupted files, which would likely result in unexpected errors such as `object not found`.\n\nFor context, clients fetch [`packfiles`](https://git-scm.com/docs/pack-protocol#_packfile_data) from upstream Git servers. Those files contain a checksum of their contents, so that clients can perform integrity checks before consuming it. The pack indexes (`.idx`) are [generated](https://git-scm.com/docs/pack-format) locally by `go-git`, or the `git` cli, when new `.pack` files are received and processed. The integrity checks for both files were not being verified correctly.\n\nNote that the lack of verification of the packfile checksum has no impact on the trust relationship between the client and server, which is enforced based on the protocol being used (e.g. TLS in the case of `https://` or known hosts for `ssh://`). In other words, the packfile checksum verification does not provide any security benefits when connecting to a malicious or compromised Git server.\n\n### Patches\n\nUsers should upgrade to `v5.16.5`, or the latest `v6` [pseudo-version](https://go.dev/ref/mod#pseudo-versions), in order to mitigate this vulnerability.\n\n### Workarounds\n\nIn case updating to a fixed version of `go-git` is not possible, users can run [git fsck](https://git-scm.com/docs/git-fsck) from the `git` cli to check for data corruption on a given repository. \n\n### Credit\n\nThanks @N0zoM1z0 for finding and reporting this issue privately to the `go-git` project.",

  "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",
