Open redirect vulnerability checklist: parameter identification, bypass techniques (URL encoding, double slashes, CRLF injection, protocol handlers), chaining with OAuth/SSRF, and impact escalation paths. Use for web app testing and bug bounty open redirect discovery.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SKILL: Open Redirect Vulnerabilities ## Metadata - **Skill Name**: open-redirect - **Folder**: offensive-open-redirect - **Source**: https://github.com/SnailSploit/offensive-checklist/blob/main/open-redirect.md ## Description Open redirect vulnerability checklist: parameter identification, bypass techniques (URL encoding, double slashes, CRLF injection, protocol handlers), chaining with OAuth/SSRF, and impact escalation paths. Use for web app testing and bug bounty open redirect discovery. ## Trigger Phrases Use this skill when the conversation involves any of: `open redirect, URL redirect, redirect bypass, URL encoding bypass, CRLF, protocol handler, redirect chain, OAuth redirect, SSRF chain, open redirection` ## Full Methodology # Open Redirect Vulnerabilities ## Shortcut - Search for redirect URL parameters. These might be vulnerable to parameter based open redirect. - Search for pages that perform referer based redirect. These are candidates for a referer based open redirect. - Test the pages and parameters you've found for open redirect. - If the server blocks the open redirect, try the protection bypass techniques mentioned before. …

How to install
mdr add miosa-osa/osa/offensive-open-redirect@sha256:89b90f0ed95a485dThe line at the top of this page pins the label git:20260913.e13b6b8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
