What authentication vulnerabilities does Pencheff test for?

Pencheff tests for brute-force susceptibility, credential stuffing exposure, weak password policy, session fixation, insecure session token entropy, missing account lockout, JWT misconfiguration, OAuth flow weaknesses, and MFA bypass techniques.

Can Pencheff test OAuth 2.0 and OIDC implementations?

Yes. Pencheff probes OAuth authorization code flows for open redirects, state parameter bypass, PKCE omission, token leakage in referrer headers, and implicit flow misuse — covering the most common OAuth security failures.

How does Pencheff test JWT security?

Pencheff tests for algorithm confusion (RS256 to HS256), the 'none' algorithm bypass, weak signing secrets, missing expiry enforcement, and signature stripping — the most common JWT vulnerabilities that allow token forgery.

ScopeDynamic Testing

Pencheff combines deterministic scanners, AI-guided probes, curated payloads, external tools, and evidence normalization so every signal lands in one remediation workflow.

OutputUnified evidence

Findings, reports, dashboards, exports, integrations, and retests all read from the same normalized record.

MethodDeterministic first

Pencheff favors repeatable checks, then uses AI for triage, enrichment, orchestration, and remediation where it adds signal.

Coverage

What does Authentication test?

Sessions, cookies, JWT, OAuth/OIDC, MFA bypass, brute force, IDOR, and privilege escalation.
This page is part of Capabilities under Dynamic Testing.
It links back into the broader from live exploits to source-code proof experience.
OSV.dev, NVD 2.0, GitHub Advisory Database, RustSec, GoVulnDB, EPSS, CISA KEV, and SSVC enrichment.
Manifest support for npm, PyPI, Go modules, Cargo, Ruby, Composer, Maven, OS packages, and container packages.
SPDX 2.3 and CycloneDX 1.5 SBOM generation with optional Syft enrichment.
Reachability annotation that separates exploited, reachable, present, and unknown risk.
License policy checks and deterministic version-bump remediation for eligible dependencies.

Execution

How does Pencheff run this?

Parse repository manifests, lockfiles, or container package inventories.
Resolve packages to advisories, fixed versions, package URLs, and known exploitation signals.
Annotate reachability from imports, call paths, runtime evidence, or scanner context.
Generate SBOM output and link component rows back to findings.
Prioritize remediation by exploitability, reachability, business criticality, and compliance impact.

Evidence

What evidence does this produce?

Package name, ecosystem, installed version, fixed version, advisory id, CVSS, EPSS, KEV, and SSVC.
SBOM component records with PURL, supplier, version, license, and dependency relationships.
Reachability state, import evidence, or reason the vulnerable component is currently only present.
Audit appendix output for procurement, compliance, and release records.

Controls

How is this kept safe to run?

Dependency risk is not sorted by CVSS alone; operational signals influence priority.
SBOM generation is repeatable and latest-generation output replaces stale records.
License and vulnerability policy can be used as release-gate input.
Version-bump fixes are deterministic when advisory metadata supports them.
