`insecure_temp_file`

CWE-377

Insecure Temp File — a PullGuard finding type. Findings of this type appear in the PR comment, Step Summary, SARIF (GitHub Security tab / IDE viewers), and the HTML report, each with severity, location, and the remediation guidance below.

How to fix

Create temp files in a private directory, not the shared system temp dir low effort

// Before: Files.createTempFile("prefix-", ".tmp")
// After:  Path dir = Files.createTempDirectory("app-");
//        Files.setPosixFilePermissions(dir, PosixFilePermissions.fromString("rwx------"));
//        Files.createTempFile(dir, "prefix-", ".tmp")

Triage

Suppress a confirmed non-issue with a committed .pullguardignore entry (pullguard ignore locally, or comment /pullguard ignore <fingerprint> <reason> on the PR — the fingerprint is printed in the PR comment’s Triage section). Entries support expiresAt for time-boxed snoozes.

Security findings at major or critical severity — and any critical finding — always surface: .pullguardignore cannot hide them. The reviewed paths that keep them visible are acknowledged (reviewed, stays in reports) and, for a confirmed false positive, a reasoned false_positive entry — visible and audited, excluded only from the merge block.
