GHSA-V5RC-CPWC-CFPR Lemur: Incomplete fix for GHSA-v2wp-frmc-5q3v -- ACME authority update endpoint allows non-admin to replace `acme_url` with internal IP, bypassing allowlist

Summary The fix for GHSA-v2wp-frmc-5q3v added validateacmeurl to reject acmeurl values not in ACMEDIRECTORYHOSTALLOWLIST, but the validation is only called at authority creation time POST. The authority update endpoint PUT /api/1/authorities/ accepts and stores arbitrary options -- including a...

CVE-2026-71303 Lemur: Incomplete fix for CVE-2026-55166 -- ACME authority update endpoint allows non-admin to replace `acme_url` with internal IP, bypassing allowlist

Lemur manages TLS certificate creation. Prior to 1.9.3, validateacmeurl enforced ACMEDIRECTORYHOSTALLOWLIST when an authority was created, but PUT /api/1/authorities/ passed options to lemur/authorities/service.py without applying the same check. A user holding an authority role could replace the...

CVE-2026-71303

In Lemur prior to 1.9.3, the PUT /api/1/authorities/ endpoint skipped the ACME_DIRECTORY_HOST_ALLOWLIST check applied at creation, letting any authority-role user set an internal or instance-metadata URL as the stored acme_url; the next issuance then made an outbound request via ClientV2.get_dire...

A server-side request forgery vulnerability in Friendica through the 2026.08-dev branch allows authenticated users with a free self-registered account to probe internal network services via the link-preview endpoint. The endpoint fetches any user-supplied URL without applying an internal IP deny...

CVE-2026-71272 Memos Webhook DNS Rebinding TOCTOU SSRF in safeDialContext()

Memos' webhook dispatch function safeDialContext internal/webhook/webhook.go resolves the target hostname via net.DefaultResolver.LookupHost and validates the resulting IPs against reserved ranges, but then dials net.JoinHostPorthost, port using the original hostname rather than the...

CVE-2026-71271

Memos' webhook URL validation, isReservedIP internal/webhook/validate.go, checks a candidate IP against a reservedCIDRs list that omits 0.0.0.0/8 and never calls ip.IsUnspecified — unlike the correctly implemented sibling function isInternalIP in internal/httpgetter/htmlmeta.go, which does...

Budibase before 3.38.1 contains a server-side request forgery vulnerability in the REST datasource integration that fails to validate HTTP redirects against the IP blacklist. Attackers with Builder role can configure a REST datasource pointing to an external server that returns a redirect to...

CVE-2026-54722

DSSRF is a Node.js library that provides a wide range of utilities and advanced SSRF defense checks. Prior to 1.0.4, isurlsafe in src/helpers.ts strips the @ userinfo delimiter with removeatsymbolinstring before new URL parses the URL, allowing an attacker-controlled URL to bypass internal-IP...

SUSE CVE-2026-55187

Mailpit is an email testing tool and API for developers. Prior to 1.30.2, the remediation shipped for CVE-2026-27808 is incomplete because the tools.IsInternalIP deny-list in internal/tools/net.go relies on Go's standard library classification helpers and does not block IPv6 transition mechanisms...

CVE-2026-54722

DSSRF (Node.js library) has a vulnerability in is_url_safe prior to version 1.0.4.

GHSA-CG4G-M8JX-VJV2 dssrf has an SSRF bypass with remove_at_symbol_in_string

Summary isurlsafe in v1.0.3 contains an SSRF bypass. removeatsymbolinstring is applied to the raw URL string before new URL parses it. This strips the @ that separates userinfo from host, corrupting the hostname so internal IPs are never checked. Vulnerability In helpers.ts, isurlsafe does: ts u ...
