Jul 16, 2026cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and using thoCVE-2026-62290 · Other software · cert-manager · reported by GitHubHigh 7.3
cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and using those certificates. From 1.18.0 until 1.19.6 and 1.20.3, Challenge resources under acme.cert-manager.io can be created directly by namespace users without admission validation tying the Challenge to an Order, owner reference, or Issuer-selected solver, allowing attacker-controlled Challenge.spec.solver values referencing a ClusterIssuer to bypass DNS01 solver selectors such as dnsZones, dnsNames, and matchLabels and cause cert-manager to use ClusterIssuer DNS credentials for attacker-selected provider settings and DNS names, including disclosure of X-Api-User and X-Api-Key headers for acme-dns. This issue is fixed in versions 1.19.6 and 1.20.3.

Feb 4, 2026cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and using thoCVE-2026-25518 · Other software · cert-manager · reported by GitHubMedium 5.9
cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and using those certificates. In versions from 1.18.0 to before 1.18.5 and from 1.19.0 to before 1.19.3, the cert-manager-controller performs DNS lookups during ACME DNS-01 processing (for zone discovery and propagation self-checks). By default, these lookups use standard unencrypted DNS. An attacker who can intercept and modify DNS traffic from the cert-manager-controller pod can insert a crafted entry into cert-manager's DNS cache. Accessing this entry will trigger a panic, resulting in denial‑of‑service (DoS) of the cert-manager controller. The issue can also be exploited if the authoritative DNS server for the domain being validated is controlled by a malicious actor. This issue has been patched in versions 1.18.5 and 1.19.3.

Dec 12, 2024A flaw was found in the cert-manager package.CVE-2024-12401 · Other software · Red Hat · reported by Red HatMedium 4.4
A flaw was found in the cert-manager package. This flaw allows an attacker who can modify PEM data that the cert-manager reads, for example, in a Secret resource, to use large amounts of CPU in the cert-manager controller pod to effectively create a denial-of-service (DoS) vector for the cert-manager in the cluster.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
