ldap_injection

CWE-90

Ldap Injection — 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

Escape LDAP metacharacters — use framework helpers low effort

// WRONG
String filter = "(cn=" + userInput + ")";

// RIGHT — Java (Spring LDAP)
EqualsFilter filter = new EqualsFilter("cn", userInput);

// RIGHT — Python (ldap3)
from ldap3.utils.conv import escape_filter_chars
filter_str = f"(cn={escape_filter_chars(user_input)})"

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.
