The tool is designed for practical web security work: bug bounty, penetration testing, security reviews, and regression testing of access-control rules. It automates a broad set of request mutations, captures a baseline, filters common false positives, and highlights the responses most likely to represent a meaningful bypass. What It Does Given a target URL, nomore403 : 1. Sends a baseline request to capture the blocked response. 2. Optionally auto-calibrates against non-existent paths to learn the target's default error behavior. 3. Runs a set of bypass techniques that mutate the request path, method, headers, or wire format. 4. Scores and groups the results to reduce noise. 5. Emits replayable evidence, including curl commands for interesting findings. This tool does not \"break authentication\" by itself. It helps find differences between how frontends, proxies, WAFs, CDNs, application routers, and backends interpret the same request. Features - Baseline-driven comparison against the blocked response - Auto-calibration to reduce false positives from default 404 or parent-path responses - Scored output with separate summaries for likely bypasses and interesting variations - Replay and reproducibility for high-value findings - Retry and backoff for transient network failures - Concurrent execution with per-technique progress -","default_branch":null,"files":null,"tree":[],"storefront":"/r/devploit","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/devploit/nomore403/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
