By leveraging encoded reserved characters such as semicolons, slashes, and backslashes, attackers can bypass configured path-based security policies to gain unauthorized access to secure administrative endpoints and static resources.\n\n## TL;DR\nQuarkus applications prior to 3.37.0 are vulnerable to an authentication bypass where encoded characters (%3B, %2F, %5C) prevent security filters from matching path-based policies, while downstream routers decode and execute the requests.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-287 / CWE-863\n- **Attack Vector**: Network\n- **CVSS v3.1 Score**: 7.5 (High)\n- **EPSS Score**: 0.00463 (37.7th percentile)\n- **Impact**: Authentication & Authorization Bypass\n- **Exploit Status**: Proof of Concept (PoC) Available\n- **CISA KEV Status**: Not Listed\n\n## Affected Systems\n\n- Quarkus Java Framework\n\n## Mitigation\n\n- Upgrade to a patched version of Quarkus (3.37.0, 3.36.3, 3.33.2.1, 3.27.4.1, 3.20.6.2)\n- Configure Web Application Firewall (WAF) or API Gateway edge rules to block encoded reserved characters (%3B, %2F, %5C)\n- Adopt programmatic method-level authorization annotations (@RolesAllowed) as a defense-in-depth measure\n\n**Remediation Steps:**\n1. Identify all Quarkus deployments within the application environment.\n2. Update application build configurations (pom.xml or build.gradle) to reference a secure, patched Quarkus version.\n3. Verify the deployment by running integration tests targeting path-based security policies.\n4. Deploy perimeter WAF rules to inspect and sanitize HTTP URIs before they reach the application cluster.\n5. Perform method-level security reviews and transition from path-based authorization to programmatic annotations where applicable.\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-50559) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-07-30T10:31:25.809792Z"}, {"uuid": "b7967b47-afd3-441a-a334-89ed8dcd525b", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-50559", "type": "seen", "source": "https://bsky.app/profile/suriq.io/post/3mooa7iyulz2r", "content": "Quarkus patched a semicolon auth bypass in May.

Verify the application version via the settings interface to ensure the patch is applied.\n\n## References\n\n- [GitHub Security Advisory GHSA-56mp-4f3v-fgj2](https://github.com/siyuan-note/siyuan/security/advisories/GHSA-56mp-4f3v-fgj2)\n- [NVD Vulnerability Detail](https://nvd.nist.gov/vuln/detail/CVE-2026-50551)\n- [CVE Authority Record](https://www.cve.org/CVERecord?id=CVE-2026-50551)\n- [Fix Merge Commit](https://github.com/siyuan-note/siyuan/commit/27e0051e0d067892e833df1063cb2fb469600e98)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-50551) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-07-11T00:01:00.222280Z"}, {"uuid": "993998b2-b1bf-4793-b6f1-9f6d2f2762cf", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-50555", "type": "seen", "source": "https://bsky.app/profile/cyberhub.blog/post/3mqj6o5bwlg2d", "content": "\ud83d\udccc CVE-2026-50555 - Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages.

The vulnerability arises due to a missing 'bail' validation rule in the Laravel-based form validation pipeline, which permits downstream HTTP checks to execute even after a URL has failed security verification.\n\n## TL;DR\nA missing validation halt keyword allows Koel's HTTP client to initiate connection probes to internal and loopback IP addresses even after the URL is marked unsafe.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-918 (Server-Side Request Forgery)\n- **Attack Vector**: Network (AV:N)\n- **CVSS v3.1 Score**: 6.3 (Medium)\n- **EPSS Score**: 0.0016\n- **EPSS Percentile**: 5.55%\n- **Exploit Status**: Proof of Concept / Public Details Available\n- **CISA KEV Status**: Not Listed\n\n## Affected Systems\n\n- Koel streaming servers deployed on private networks or hosting platforms.\n- **Koel**: < 9.7.1 (Fixed in: `9.7.1`)\n\n## Mitigation\n\n- Upgrade the Koel application instance to version 9.7.1 or higher to enforce proper validation termination.\n- Restrict outbound network access from the Koel application container to internal subnets (RFC 1918) and the local loopback interface.\n- Utilize Web Application Firewall (WAF) rules to detect and reject validation requests containing internal IP configurations.\n\n**Remediation Steps:**\n1. Navigate to the root directory of the Koel deployment.\n2. Pull the latest codebase updates using the repository manager: git pull origin master\n3. Re-install dependencies using Composer: composer install --no-dev\n4. Synchronize system state using the Artisan command-line tool: php artisan koel:sync\n\n## References\n\n- [GitHub Security Advisory GHSA-jr4p-4xjh-fwvw](https://github.com/koel/koel/security/advisories/GHSA-jr4p-4xjh-fwvw)\n- [Official Fix Commit](https://github.com/koel/koel/commit/5f6ce2cefd08f437a269236b677ad971517ccbb6)\n- [CVE Record Database](https://www.cve.org/CVERecord?id=CVE-2026-50552)\n- [NVD Vulnerability Detail](https://nvd.nist.gov/vuln/detail/CVE-2026-50552)\n- [Koel Release v9.7.1](https://github.com/koel/koel/releases/tag/v9.7.1)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-50552) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-07-15T19:31:25.216249Z"}, {"uuid": "6308a6da-28be-478c-a0b4-d8dbc24861a6", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2026-50552", "type": "published-proof-of-concept", "source": "https://github.com/koel/koel/security/advisories/GHSA-jr4p-4xjh-fwvw", "content": "", "creation_timestamp": "2026-07-15T20:35:05.454179Z"}, {"uuid": "efef84e9-8b2a-411e-9e0b-6b749bf89669", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2026-50559", "type": "published-proof-of-concept", "source": "https://github.com/quarkusio/quarkus/security/advisories/GHSA-qcxp-gm7m-4j5v", "content": "", "creation_timestamp": "2026-07-29T16:35:02.695583Z"}, {"uuid": "a2b2d3cb-5c8d-453b-a363-dec6fe814a32", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2026-50558", "type": "published-proof-of-concept", "source": "https://github.com/brightio/penelope/security/advisories/GHSA-f42x-p2mx-hm8r", "content": "", "creation_timestamp": "2026-07-29T16:35:05.097640Z"}]}
