Security Audit Report for specifyjs: URL Bypass, GraphQL Injection, SSRF, Prototype Pollution

Vulnerability Overview The web page screenshot displays a security audit report for the project, listing multiple security vulnerabilities with detailed information. The primary vulnerabilities include: 1. PT-001: URL Parse Failure Silently Allows Request (High) - Description: When throws a parsing error, the function silently allows the request, bypassing HTTPS validation. - Impact: An attacker can construct a failing URL to bypass HTTPS validation policies. - Remediation: Throw an error in the block instead of silently allowing the request. 2. PT-002: GraphQL gql Tag Allows Metacharacter Injection (Medium) - Description: The template tag function warns when interpolated values contain GraphQL metacharacters but still concatenates them into the query string, potentially leading to GraphQL injection vulnerabilities. - Impact: Attackers can inject malicious GraphQL queries via the tag. - Remediation: Throw an error when metacharacters are detected, or completely remove interpolation functionality from . 3. PT-003: CSS Expression Sanitization Is Bypassable (Medium) - Description: CSS value sanitization strips and , but this can be bypassed using CSS escapes, null bytes, or CSS comments. - Impact: Attackers can bypass CSS value sanitization to execute malicious CSS expressions. - Remediation: Use a stricter approach to reject CSS values containing suspicious patterns rather than attempting sanitization. 4. PT-004: No Redirect Target Validation in secureFetch (Medium) - Description: only validates the initial request URL. The API follows redirects by default (up to 20 times), potentially leading to redirects to internal services or other unvalidated targets. - Impact: Attackers can redirect requests to unvalidated targets. - Remediation: Disable automatic redirect following for sensitive contexts, or validate the header before following redirects. 5. PT-005: data: URI Allowed Without Restriction (Medium) - Description: URIs are allowed without restriction. Although URIs do not initiate network requests, they can be used for memory exhaustion (very large data URIs) or encoding malicious content for consumption by other consumers. - Impact: Attackers can leverage URIs for memory exhaustion or to encode malicious content. - Remediation: Add size limits for data URIs. 6. PT-006: dangerouslySetInnerHTML Passes Raw HTML (Low) - Description: By design, the React API matches , injecting raw HTML without sanitization. - Impact: Attackers can inject malicious HTML via . - Remediation: No code changes are required, as this is intended API behavior. Consider adding a dev-time warning if the HTML includes tags or event handlers. 7. PT-007: cloneElement Missing constructor/prototype Guard (Low) - Description: only filters from config props, whereas filters , , and . This inconsistency could lead to prototype pollution if is used with untrusted config objects. - Impact: Attackers can perform prototype pollution via . - Remediation: Add the missing guards in at line 43. 8. PT-008: Localhost Bypass Incomplete (Low) - Description: The exception allows and , but does not cover , (IPv6 localhost), or the entire loopback range. - Impact: Attackers can bypass security policies using uncovered localhost addresses. - Remediation: Expand localhost detection to cover , , and . Scope of Impact High Risk: PT-001 Medium Risk: PT-002, PT-003, PT-004, PT-005 Low Risk: PT-006, PT-007, PT-008 Remediation 1. PT-001: Remediated to: 2. PT-002: Remediated to: 3. PT-003: Remediated to: 4. PT-004: Remediated to: Or use and validate the header before following redirects. 5. PT-005: Remediated to: 6. PT-006: 7. PT-007: 8. PT-008: Summary This security audit report details multiple vulnerabilities in the project, including URL parse failures, GraphQL injection, CSS expression bypasses, lack of redirect target validation, unrestricted allowance of data: URIs, passing of raw HTML, prototype pollution, and localhost bypasses. Specific impacts and remediation solutions are provided for each vulnerability to help developers fix these issues promptly and enhance project security.
