Reuse the released in-repository pinned HTTPS transport so validation and connection share one immutable address set on every redirect. Reject HTTP, malformed ports, unresolved/non-global destinations, and missing webhook URL fields while preserving explicit null and empty-string deletion.

💡 **Vulnerability:** The internal \`set_webhook\` database function did not independently validate the given \`webhook_url\` for SSRF safety. It relied entirely on the HTTP handler \`/api/v1/webhook\` to validate URLs via \`_is_safe_url\`. 🎯 **Impact:** If internal functions dynamically call \`set_webhook\` bypassing the HTTP presentation layer, they can inadvertently save unsafe URLs (e.g., localhost endpoints), leading to stored SSRF vulnerabilities when the system attempts to send drift alerts. 🔧 **Fix:** - Moved \`_is_safe_url\` validation down directly into \`set_webhook\` as a strict defense-in-depth measure to prevent unsafe webhook URLs from reaching the database regardless of entry point. - Handled empty string \`\"\"\` by normalizing to \`None\` to ensure explicit clear operations bypass URL validation. - Updated the HTTP handler to gracefully handle \`ValueError\` raised by \`set_webhook\` during invalid validations and return an appropriate 400 response. - Updated the \`python-stored-ssrf-webhook-url\` rule regex to properly identify when \`set_webhook\` is safely guarded by catching \`ValueError\` specifically linked to the target webhook_url, and skip over unrelated \`set_webhook\` checks that bypass earlier try blocks. ✅ **Verification:** - Ran the full AppGuardrail unit and integration testing suite (\`uv run pytest tests/\`). - Verified that existing contracts for clearing webhooks and receiving malformed payloads passed with no regressions.

Retain Issue #850 as an executable regression family after the canonical EgressWeave repair. Detect the bounded global allow_local -> loopback Boolean-admission shape, keep hostname-bound and non-admitting flows negative, and record exact vulnerable/fixed owner evidence plus the immutable-release gap.
Update the canonical buyer-facing baseline with PR #1327 exact detector blobs, executable positive/negative boundaries, hosted test and gate evidence, and the remaining CodeQL, review, immutable owner-release, and consumer-version gaps.

The minimal repair exempts only an explicitly local configuration attribute when the guard precedes and dominates the actual local-address admission branch.Review found and repaired two over-broad variants before publication: generic
allowed_hosts/ trusted collections remain positive because remote names can rebind; later and conditionally nested guards remain positive because they do not dominate admission. A nested observation-onlyallow_localcheck before a real dominating guard remains negative. The atomic function-signature boundary prevents regex backtracking from consuming the guard as a false signature terminator.Verification on the exact tree:

Concurrent regression RCA and recovery
Commit
a6206bac…was an ordinary child of the previously verifiedc5719d2…, but its actual diff deleted the Issue #1267 DNS validation-to-connect rule, its 403-line regression module and detector contract, removed architecture/PRD/traceability/changelog claims, and restored divergent string/Path language parsing. Its commit message claimed database-boundary work, while its parent diff contained no database or webhook source/test addition.Recovery commit
70c831ac…preservesa6206bac…in ancestry and restores the exact previously reviewed tree58a985d1…. This is delta integration, not history rewriting. The exact tree comparison is clean and the independent staged-delta review found no Critical or Important issue.Commit
0d2bf6f0…later repeated the same stale-snapshot class: it again deleted the DNS TOCTOU rule, its 403-line corpus and detector document, removed PRD/Architecture/traceability/changelog evidence, and restored the divergent language parser. Its message again claimed DB-boundary work while the actual diff contained no control-plane DB/webhook implementation or regression. Ordinary childb42071a2…preserves that commit in ancestry, restores every verified delta, and adds the separately reviewed DNS fail-open detector corpus.Commit
0fa9549f…repeated the same stale-snapshot deletion a third time: it removed both Issue #1267 detector rules, 748 lines of executable corpus, both detector contracts and current architecture/PRD/traceability evidence, and restored divergent string/Pathparsing. Its DB-boundary message again had no DB/webhook implementation or test delta. Ordinary child3d1b3d85…preserves0fa9549f…in ancestry and restores exact verified tree31e47e0e…without Force Push. Concurrent childrencc08d337…,67b42a1a…, and73cf780f…preserve that ancestry and the identical tree (zero file delta); their messages restate the already-carried database-boundary repair, so no source evidence is transferred or discarded.Runtime and detector contract
The webhook repair uses
post_json_pinned_https: one admitted address set per HTTPS hop, rejection of mixed/non-global answers, pinned TCP peer, original hostname for TLS SNI/certificate verification, bounded redirects/responses, and explicit response closure.The retained HIGH rule

New HIGH rulepython-ssrf-hostname-unbound-local-address-exceptionmaps Issue #850 to CWE-918 and detects address-policy functions whose standalone globalallow_localbranch directly admits loopback through a Boolean flag without binding the exception to the original hostname.Source identities:
