A security testing guide for authentication bypasses, where someone reaches an account or protected feature without completing the required login checks.

In plain words
What is it for?
Use it to examine SAML, OAuth, OIDC, WordPress XML-RPC, admin portals, partner portals, and API authentication.
Why use it?
It helps find gaps in single sign-on, OAuth, API, plugin, and administrative login flows.

SkillSpector: 3 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Privilege Escalation · line 137
    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
  • high Prompt Injection · line 197
    Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.
    Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
  • medium Data Exfiltration · line 159
    Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
    Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hunt-auth-bypass scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

The opening of the file, as written. The whole thing — 326 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Crown Jewel Targets

Auth bypass is consistently one of the highest-paying vulnerability classes in bug bounty because it directly violates the most fundamental security control. High-value targets include:

  • SSO/SAML implementations at enterprise SaaS companies (Slack, Okta, OneLogin integrations) — payouts regularly in the $5K–$25K+ range
  • Admin panels and partner/internal portals — subdomain-separated admin surfaces like partners.shopify.com, admin.company.com
  • Third-party auth plugin integrations — WordPress plugins (OneLogin, WP-SAML-Auth), Drupal SSO modules, any CMS with pluggable auth
  • XMLRPC endpoints on WordPress — often forgotten, bypasses standard WP auth flows entirely
  • OAuth callback flows — state parameter mishandling, redirect_uri mismatches
  • API authentication layers — especially where auth was bolted on after the fact

Asset priority: Targets with federated identity (SAML, OAuth, OIDC) connected to large user populations. Partner/reseller portals are particularly juicy because they often have elevated permissions and less security scrutiny than the main product.


Attack Surface Signals

URL patterns to hunt:

/xmlrpc.php
/wp-login.php
/saml/
/sso/
/auth/saml/callback
/oauth/callback
/partners.*
/admin.*
/?wc-api=
/api/v*/auth
/login?redirect=
/accounts/login

Response headers signaling SSO:

X-Frame-Options: SAMEORIGIN (common on SSO portals)
Set-Cookie: SAMLResponse=
Location: https://idp.company.com/saml
WWW-Authenticate: Bearer realm="partners"

JS patterns indicating federated auth:

// Look for in page source
samlRequest
RelayState
SAMLResponse
onelogin
shibboleth
okta
passport.js authenticate

Tech stack signals:

  • WordPress + any SSO plugin → check XMLRPC separately
  • Shopify Partner API exposure → cross-tenant privilege escalation risk
  • Any app advertising "SSO enabled" or "Login with [Enterprise IdP]"
  • Separate subdomains for admin/partner that share session cookies with main domain
  • Applications using SimpleSAMLphp, ruby-saml, python-saml

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
