  "details": "### Summary\nAn unprotected user enumeration vulnerability exists in the account email update endpoint, allowing authenticated users to verify whether email addresses are registered on the panel through automated requests without rate limiting or CAPTCHA protection.\n\n### Details\nThe account settings page allows authenticated users to update their email address through a POST request. Unlike the login and password reset forms which implement reCAPTCHA and rate limiting protections, this endpoint lacks these safeguards entirely.\nAn attacker can capture the email update request (for example, using Burp Suite\u0027s proxy) and modify the email field to test arbitrary addresses. The panel\u0027s response will confirm whether each tested email is already registered in the system. Because there are no rate limits implemented, attackers can send hundreds or thousands of requests to enumerate the user base.\n\nThis is concerning because:\n\n- The login and password reset pages correctly implement protections against enumeration\n- The account page has no reCAPTCHA option available\n- No rate limiting exists in the panel for this endpoint\n- Authentication is required, but any valid account (including free tier/trial accounts) can exploit this\n\n### PoC\n- Log into the Pterodactyl panel with any valid account\n- Navigate to Account Settings\n- Open Burp Suite (or similar proxy tool) and configure your browser to proxy through it\n- Attempt to change your email address and capture the POST request\n- Send the captured request to Repeater\n- Modify the email field to test different addresses (e.g., admin@example.com, test@example.com)\n- Send multiple requests in rapid succession\n- Observe the response messages which confirm whether each email exists or not \n- Repeat indefinitely without encountering rate limits or CAPTCHA challenges\n\n\n### Impact\nThis is a user enumeration vulnerability (CWE-204: Observable Response Discrepancy).\n\nWho is impacted:\n\n- All Pterodactyl panel installations are affected\n- Any registered user\u0027s email address can be discovered\n- Particularly impacts administrators and high-value accounts\n\nPotential consequences:\n\n- Attackers can build a complete database of registered users\n- Enumerated emails can be used for targeted phishing campaigns\n- Combined with other attacks (credential stuffing, social engineering)\n- Privacy violation for all users on the platform\n- Competitive intelligence gathering (identifying which companies/individuals use specific panels)",

  "details": "### Impact\n_What kind of vulnerability is it? Who is impacted?_\n\nMinIO AIStor\u0027s STS (Security Token Service) `AssumeRoleWithLDAPIdentity` endpoint is vulnerable to LDAP credential brute-forcing due to two combined weaknesses: (1) distinguishable error responses that enable username enumeration, and (2) absence of rate limiting on authentication attempts. An unauthenticated network attacker can enumerate valid LDAP usernames and then perform unlimited password guessing to obtain temporary AWS-style STS credentials, gaining access to the victim\u0027s S3 buckets and objects.\n\nAll deployments with LDAP configured running an affected version are impacted.\n\nThere are two vulnerabilities:\n\n1. User Enumeration via Distinguishable Error Messages (CWE-204)\n2. Missing Rate Limiting on STS Authentication Endpoints (CWE-307)\n\nWhen exploited together, an attacker can:\n\n1. Enumerate valid LDAP usernames by observing error message differences.\n3. Perform high-speed password brute-force attacks against confirmed valid users.\n4. Upon finding valid credentials, obtain temporary AWS-style STS credentials (`AccessKeyId`, `SecretAccessKey`, `SessionToken`) with full access to the victim user\u0027s S3 resources.\n\n### Affected Versions\n\nAll MinIO releases through the final release of the minio/minio open-source project.\n\n### Patches\n\n**Fixed in**: MinIO AIStor RELEASE.2026-03-17T21-25-16Z\n\n#### Binary Downloads\n\n| Platform | Architecture | Download                                                                    |\n| -------- | ------------ | --------------------------------------------------------------------------- |\n| Linux    | amd64        | [minio](https://dl.min.io/aistor/minio/release/linux-amd64/minio)           |\n| Linux    | arm64        | [minio](https://dl.min.io/aistor/minio/release/linux-arm64/minio)           |\n| macOS    | arm64        | [minio](https://dl.min.io/aistor/minio/release/darwin-arm64/minio)          |\n| macOS    | amd64        | [minio](https://dl.min.io/aistor/minio/release/darwin-amd64/minio)          |\n| Windows  | amd64        | [minio.exe](https://dl.min.io/aistor/minio/release/windows-amd64/minio.exe) |\n\n#### FIPS Binaries\n\n| Platform | Architecture | Download                                                                    |\n| -------- | ------------ | --------------------------------------------------------------------------- |\n| Linux    | amd64        | [minio.fips](https://dl.min.io/aistor/minio/release/linux-amd64/minio.fips) |\n| Linux    | arm64        | [minio.fips](https://dl.min.io/aistor/minio/release/linux-arm64/minio.fips) |\n\n#### Package Downloads\n\n| Format | Architecture | Download                                                                                                                            |\n| ------ | ------------ | ----------------------------------------------------------------------------------------------------------------------------------- |\n| DEB    | amd64        | [minio_20260317212516.0.0_amd64.deb](https://dl.min.io/aistor/minio/release/linux-amd64/minio_20260317212516.0.0_amd64.deb)         |\n| DEB    | arm64        | [minio_20260317212516.0.0_arm64.deb](https://dl.min.io/aistor/minio/release/linux-arm64/minio_20260317212516.0.0_arm64.deb)         |\n| RPM    | amd64        | [minio-20260317212516.0.0-1.x86_64.rpm](https://dl.min.io/aistor/minio/release/linux-amd64/minio-20260317212516.0.0-1.x86_64.rpm)   |\n| RPM    | arm64        | [minio-20260317212516.0.0-1.aarch64.rpm](https://dl.min.io/aistor/minio/release/linux-arm64/minio-20260317212516.0.0-1.aarch64.rpm) |\n\n#### Container Images\n\n```bash\n# Standard\ndocker pull quay.io/minio/aistor/minio:RELEASE.2026-03-17T21-25-16Z\npodman pull quay.io/minio/aistor/minio:RELEASE.2026-03-17T21-25-16Z\n\n# FIPS\ndocker pull quay.io/minio/aistor/minio:RELEASE.2026-03-17T21-25-16Z.fips\npodman pull quay.io/minio/aistor/minio:RELEASE.2026-03-17T21-25-16Z.fips\n```\n\n#### Homebrew (macOS)\n\n```bash\nbrew install minio/aistor/minio\n```\n \n\n### Workarounds\n\n- [Users of the open-source `minio/minio` project should upgrade to MinIO AIStor `RELEASE.2026-03-17T21-25-16Z` or later.](https://docs.min.io/enterprise/aistor-object-store/upgrade-aistor-server/community-edition/)\n\nIf upgrading is not immediately possible:\n\n- **Network-level rate limiting**: Use a reverse proxy (e.g., nginx, HAProxy) or WAF to rate-limit requests to the `/?Action=AssumeRoleWithLDAPIdentity` endpoint.\n- **Firewall restrictions**: Restrict access to the STS endpoint to trusted networks/IP ranges only.\n- **LDAP account lockout**: Configure account lockout policies on the LDAP server itself (e.g., Active Directory lockout threshold). Note: this protects against brute-force but not enumeration, and may cause denial-of-service for legitimate users.",

  "details": "A vulnerability in the web-based management interface of Cisco\u0026nbsp;ECE could allow an unauthenticated, remote attacker to perform a username enumeration attack against an affected device.\n\nThis vulnerability is due to differences in authentication responses that are sent back from the application as part of an authentication attempt. An attacker could exploit this vulnerability by sending authentication requests to an affected device. A successful exploit could allow the attacker to confirm existing user accounts, which could be used in further attacks.\nCisco\u0026nbsp;has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.",
