Argo CD v2.11.3 and before, discovering that even if the user's p, role:myrole, exec, create, /, allow permissions are revoked, the user can still send any Websocket message, which allows the user to view sensitive information. Even though they shouldn't have such access.
This report details a security vulnerability in Argo CD, where an unauthenticated attacker can send a specially crafted large JSON payload to the /api/webhook endpoint, causing excessive memory allocation that leads to service disruption by triggering an Out Of Memory (OOM) kill. The issue poses a high risk to the availability of Argo CD deployments.
The CVE allows unauthorized access to the sensitive settings exposed by /api/v1/settings endpoint without authentication.
By default, the Redis database server is not password-protected. Consequently, an attacker with access to the Redis server can gain read/write access to the data in Redis. The attacker can also modify the "mfst" (manifest) key to cause ArgoCD to execute any deployment, potentially leveraging ArgoCD's high privileges to take over the cluster. Updating the "cacheEntryHash" in the manifest JSON is necessary, but since it doesn't use a private key …

All versions of ArgoCD starting from v2.4 have a bug where the ArgoCD repo-server component is vulnerable to a Denial-of-Service attack vector. Specifically, it's possible to crash the repo server component through an out of memory error by pointing it to a malicious Helm registry. The loadRepoIndex() function in the ArgoCD's helm package, does not limit the size nor time while fetching the data. It fetches it and creates a …
An attacker can exploit a critical flaw in the application to initiate a Denial of Service (DoS) attack, rendering the application inoperable and affecting all users. The issue arises from unsafe manipulation of an array in a multi-threaded environment.
An attacker can effectively bypass the rate limit and brute force protections by exploiting the application's weak cache-based mechanism. This loophole in security can be combined with other vulnerabilities to attack the default admin account. This flaw undermines a previously patched CVE intended to protect against brute-force attacks.
An attacker can exploit a chain of vulnerabilities, including a Denial of Service (DoS) flaw and in-memory data storage weakness, to effectively bypass the application's brute force login protection. This makes the application susceptible to brute force attacks, compromising the security of all user accounts.
Impact "Local sync" is an Argo CD feature that allows developers to temporarily override an Application's manifests with locally-defined manifests. Use of the feature should generally be limited to highly-trusted users, since it allows the user to bypass any merge protections in git. An improper validation bug allows users who have create privileges but not override privileges to sync local manifests on app creation. All other restrictions, including AppProject restrictions …
Summary Due to the improper URL protocols filtering of links specified in the link.argocd.argoproj.io annotations in the application summary component, an attacker can achieve cross-site scripting with elevated permissions. Impact All unpatched versions of Argo CD starting with v1.0.0 are vulnerable to a cross-site scripting (XSS) bug allowing a malicious user to inject a javascript: link in the UI. When clicked by a victim user, the script will execute with …
