Secure SDLC practices directly require input validation and path sanitization that prevent absolute path traversal.

A.8.25 mandates secure SDLC practices (secure requirements, checkpoints, secure coding guidelines, testing including code scans/penetration tests) that reach many path-traversal instances in custom software, but leaves a bounded remainder (e.g. third-party components, misconfigured outsourced development, or incomplete enforcement of guidelines) where the weakness can still be introduced and exploited.
Application security requirements typically mandate controls against path traversal in file-access functions.
A.8.27 mandates security-by-design principles (least privilege, default-deny, distrust-external-input, hardening, design review against attack patterns) that reach a minority slice of absolute path traversal (e.g. explicit path canonicalization rules or sandboxing), but most instances arise from ordinary string-concatenation flaws in custom code that the clause's high-level engineering principles do not themselves stop from being written or exploited.
Secure coding standards directly require neutralization of absolute path sequences in pathname construction.
Security testing in development can detect absolute path traversal via static analysis and fuzzing.
