| CVE-2026-44309 | 2026-05-18 | N/A | 5.3 MEDIUM | ||
| Gitsign is a keyless Sigstore to signing tool for Git commits with your a GitHub / OIDC identity. Prior to 0.16.0, gitsign verify and gitsign verify-tag re-encode commit/tag objects through go-git's EncodeWithoutSignature before checking the signature, instead of verifying against the raw git object bytes. For malformed objects with duplicate tree headers, git-core and go-git parse different trees: git-core uses the first, go-git uses the second. A signature crafted over the go-git-normalized form (second tree) passes gitsign verify while git-core resolves the commit to a completely different tree. This breaks the invariant that a verified signature, the commit semantics git-core presents to users, and the object hash logged in Rekor all refer to the same content. This vulnerability is fixed in 0.16.0. | |||||
| CVE-2025-10539 | 1 Draugiemgroup | 1 Desktime Time Tracking | 2026-05-18 | N/A | 4.8 MEDIUM |
| Due to improper TLS certificate validation in the DeskTime Time Tracking App before version 1.3.674, attackers who can position themselves in the network path between the client and the DeskTime update servers can return a malicious executable in response to an update request. This allows the attacker to achieve user-level remote code execution on the affected client. | |||||
| CVE-2026-41119 | 2026-05-18 | N/A | 6.8 MEDIUM | ||
| Dell Live Optics Windows and Personal Edition collectors contain an improper certificate validation vulnerability. A remote unauthenticated attacker could potentially exploit this vulnerability leading to loss of confidentiality and integrity. | |||||
| CVE-2026-44312 | 2026-05-15 | N/A | 5.8 MEDIUM | ||
| css_parser is a Ruby CSS parser. Prior to 2.1.0 and 1.22.0, the CSS Parser gem does not validate HTTPS connections, allowing a Man-in-the-Middle (MITM) attacker to inject or modify CSS content when stylesheets are loaded via HTTPS. The connection is established with OpenSSL::SSL::VERIFY_NONE, meaning any HTTPS certificate—even entirely untrusted—will be accepted without validation. This vulnerability is fixed in 2.1.0 and 1.22.0. | |||||
| CVE-2026-23998 | 1 Fleetdm | 1 Fleet | 2026-05-15 | N/A | 7.5 HIGH |
| Fleet is open source device management software. Prior to version 4.81.0, a vulnerability in Fleet’s Windows MDM management endpoint could allow requests to be processed without proper client certificate validation. In certain circumstances, this could allow an attacker to impersonate an enrolled Windows device and retrieve sensitive configuration data. Fleet’s Windows MDM management endpoint relies on mutual TLS (mTLS) client certificates to authenticate enrolled devices. In affected versions, requests that did not present a client certificate could be incorrectly treated as trusted. As a result, an attacker with prior knowledge of a valid enrolled device identifier could potentially impersonate that device and receive configuration payloads intended for it. These payloads may contain sensitive information such as Wi-Fi or VPN configuration data, certificates, or other secrets delivered through MDM profiles. This issue does not allow enrollment of new devices, administrative access to Fleet, or compromise of the Fleet control plane. Impact is limited to the targeted Windows device. Version 4.81.0 contains a patch. If an immediate upgrade is not possible, affected Fleet users should temporarily disable Windows MDM. | |||||
| CVE-2026-41132 | 1 Okfn | 1 Ckan | 2026-05-15 | N/A | 7.4 HIGH |
| CKAN is an open-source DMS (data management system) for powering data hubs and data portals. Prior to 2.10.10 and 2.11.5, the configured SMTP server may be spoofed with any certificate (e.g. self-signed), leaving credentials and all emails sent open to MITM attacks. This vulnerability is fixed in 2.10.10 and 2.11.5. | |||||
| CVE-2026-44700 | 2026-05-15 | N/A | N/A | ||
| Elixir WebRTC is an Elixir implementation of the W3C WebRTC API. Prior to 0.15.1 and 0.16.1, missing DTLS peer certificate fingerprint validation in the DTLS client (active) role removes one side of WebRTC's mutual authentication. The bug is not independently exploitable for media interception in standard deployments, but enables a full man-in-the-middle attack when chained with insecure signalling or a peer with similar validation gaps. This vulnerability is fixed in 0.15.1 and 0.16.1. | |||||
| CVE-2026-42312 | 1 Pyload-ng Project | 1 Pyload-ng | 2026-05-15 | N/A | 6.8 MEDIUM |
| pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev100, the set_config_value() API method (@permission(Perms.SETTINGS)) in src/pyload/core/api/__init__.py gates security-sensitive options behind a hand-maintained allowlist ADMIN_ONLY_CORE_OPTIONS. The option ("general", "ssl_verify") is not on that allowlist. Any authenticated user with the non-admin SETTINGS permission can set general.ssl_verify = off, and every subsequent outbound pycurl request is made with SSL_VERIFYPEER=0 and SSL_VERIFYHOST=0 — TLS peer and hostname verification are fully disabled. An on-path attacker can then present forged certificates for any hostname pyload fetches. This is a direct continuation of the fix family CVE-2026-33509 / CVE-2026-35463 / CVE-2026-35464 / CVE-2026-35586, each of which patched a different missed option in the same allowlist. This vulnerability is fixed in 0.5.0b3.dev100. | |||||
| CVE-2026-42011 | 2026-05-14 | N/A | 7.4 HIGH | ||
| A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems. | |||||
| CVE-2026-32992 | 2026-05-14 | N/A | 8.2 HIGH | ||
| SSL verification is disabled in the DNS Cluster system. This could allow for a malicious server to man-in-the-middle the request and capture credentials. | |||||
| CVE-2026-44363 | 2026-05-14 | N/A | N/A | ||
| MISP modules are autonomous modules that can be used to extend MISP for new services. Prior to 3.0.7, an unsafe remote resource fetching vulnerability existed in MISP Modules expansion modules. The html_to_markdown module accepted arbitrary HTTP(S) URLs without sufficient validation, which could allow Server-Side Request Forgery against loopback, private, or link-local network resources. Additionally, the qrcode module disabled TLS certificate verification when retrieving remote images, exposing requests to potential man-in-the-middle interception or response tampering. The issue was fixed by validating URL schemes, blocking local and private address ranges, resolving hostnames before fetching, enforcing request timeouts, and re-enabling TLS certificate verification. This vulnerability is fixed in 3.0.7. | |||||
| CVE-2026-0248 | 2026-05-14 | N/A | N/A | ||
| An improper certificate validation vulnerability in the Prisma Access Agent® for Android and Chrome OS enables an attacker to perform a man-in-the-middle (MitM) attack to intercept VPN traffic. By presenting a certificate for any domain issued by a trusted Certificate Authority, the attacker can capture sensitive device information. The Prisma Access Agent on macOS, Windows, Linux and iOS are not affected. | |||||
| CVE-2026-0244 | 2026-05-14 | N/A | N/A | ||
| An improper certificate validation vulnerability in the Palo Alto Networks Prisma SD-WAN ION enables man-in-the-middle (MitM) attacker to impersonate the controller. | |||||
| CVE-2026-0249 | 2026-05-14 | N/A | N/A | ||
| Multiple improper certificate validation vulnerabilities in the Palo Alto Networks GlobalProtect™ app enables an attacker to intercept encrypted communications and potentially compromise the endpoint. This can enable a local non-administrative operating system user or an attacker on the same subnet to redirect traffic to an unauthorized server and facilitate the installation of malicious software. The GlobalProtect app on Linux, Windows, iOS and GlobalProtect UWP app are not affected. | |||||
| CVE-2026-40970 | 1 Vmware | 1 Spring Boot | 2026-05-14 | N/A | 5.0 MEDIUM |
| When configured to use an SSL bundle, Spring Boot's Elasticsearch auto-configuration does not perform hostname verification when connecting to the Elasticsearch server. Affected: Spring Boot 4.0.0–4.0.5; upgrade to 4.0.6 or later per vendor advisory. | |||||
| CVE-2026-40971 | 1 Vmware | 1 Spring Boot | 2026-05-14 | N/A | 5.0 MEDIUM |
| When configured to use an SSL bundle, Spring Boot's RabbitMQ auto-configuration does not perform hostname verification when connecting to the RabbitMQ broker. Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14) per vendor advisory. | |||||
| CVE-2026-40974 | 1 Vmware | 1 Spring Boot | 2026-05-14 | N/A | 5.0 MEDIUM |
| Spring Boot's Cassandra auto-configuration does not perform hostname verification when establishing an SSL connection to Cassandra. Affected: Spring Boot 4.0.0–4.0.5 (fix 4.0.6), 3.5.0–3.5.13 (fix 3.5.14), 3.4.0–3.4.15 (fix 3.4.16), 3.3.0–3.3.18 (fix 3.3.19), 2.7.0–2.7.32 (fix 2.7.33); Cassandra SSL auto-configuration. Versions that are no longer supported are also affected per vendor advisory. | |||||
| CVE-2026-7009 | 1 Haxx | 1 Curl | 2026-05-14 | N/A | 5.3 MEDIUM |
| When curl is told to use the Certificate Status Request TLS extension, often referred to as *OCSP stapling*, to verify that the server certificate is valid, it fails to detect OCSP problems and instead wrongly consider the response as fine. | |||||
| CVE-2026-4873 | 1 Haxx | 1 Curl | 2026-05-14 | N/A | 5.9 MEDIUM |
| A vulnerability exists where a connection requiring TLS incorrectly reuses an existing unencrypted connection from the same connection pool. If an initial transfer is made in clear-text (via IMAP, SMTP, or POP3), a subsequent request to that same host bypasses the TLS requirement and instead transmit data unencrypted. | |||||
| CVE-2026-44305 | 2026-05-13 | N/A | 6.8 MEDIUM | ||
| 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. | |||||
