Lemur manages TLS certificate creation. Prior to 1.9.0, when LDAP TLS is enabled (LDAP_USE_TLS = True), Lemur's LDAP authentication module unconditionally disables TLS certificate verification at the global ldap module level. This allows a man-in-the-middle attacker positioned between Lemur and the LDAP server to intercept all authentication credentials. This vulnerability is fixed in 1.9.0.

CVE-2026-105031——
——0When using the OpenSSL TLS implementation, both the pn_ssl_domain_set_trusted_ca_db() & pn_tls_config_set_trusted_certs() APIs added to rather than replaced the default system trust anchors. Leading to potentially trusting unexpected peer certificates.
This can be worked around by setting the SSL_CERT_FILE environment variable for the application to /dev/null.
This issue does not affect the Win32 SChannel TLS implementation.
This issue affects Apache Qpid Proton C: through 0.40.0.
Users are recommended to upgrade to version 0.41.1, which fixes the issue.55mCVE-2026-117611——
——0Improper certificate validation in Checkmk <2.5.0p18, <2.4.0p39, <2.3.0p52 and 2.2.0 (EOL): the Certificate Authority stores bundled with "certifi" and "webpki-roots" include a root CA that trusts eMudhra (emSign) intermediate certificates whose private keys are public.2hCVE-2026-1186827.5 HIG—
——0KaringX ClashMi through 1.0.32.1801 disables TLS certificate validation by default in the HttpUtils helper, allowing attackers to intercept HTTPS traffic by presenting any certificate. Attackers operating the user's proxy node can serve a forged update manifest omitting sha256 to deliver a malicious installer, achieving code execution when the update runs.14hCVE-2026-1166416.8 MED—
——0The DB Tools rely on the TLS implementation in Golang’s standard library, which generally uses the system CA store. However, the crypto/x509 package also has its own internal denylist of known-bad CA certificates. Golang 1.27.3 adds the eMudhra certificates to this list.
DB Tools version 100.19.0 was compiled with Golang 1.26.8, which does not include this check.
The issue is resolved by updating to Golang 1.27.3 in DB Tools 100.20.014hCVE-2026-1180407.5 HIG—
——0In Progress® Telerik® Document Processing Libraries prior to version 2026.3.1027, improper verification of cryptographic signatures and improper certificate validation in RadPdfProcessing digital signature validation allow an unauthenticated attacker to cause signature validation to report forged content as unmodified and its signing certificate as valid via a crafted signed PDF document.22hCVE-2026-878806.8 MED—
——0Sensitive information disclosure due to missing SSL certificate verification affecting one component. The following products are affected: Acronis Cyber Protect 17 (Linux, Windows) before build 42587.54m
