The Steeltoe.Discovery.Eureka client contains a vulnerability (CVE-2026-50196) where its `DataCenterInfo.FromJson` method throws an `ArgumentException` if a `DataCenterInfo.name` value other than 'MyOwn' or 'Amazon' is encountered, specifically missing the valid 'Netflix' value from the Java Eureka specification, which causes the local service registry to become permanently empty or stale, leading to a complete service discovery outage for all connected Steeltoe Eureka clients.

A high-severity vulnerability, CVE-2026-50200, in the Steeltoe `Sanitizer` component of the Environment actuator allows for the unintended disclosure of sensitive connection string values, including embedded plaintext credentials, when the `/actuator/env` endpoint is accessed, enabling direct database connection and bypassing application-tier security.

Algernon, when running on a Windows host, is vulnerable to CVE-2026-52792, allowing an unauthenticated attacker to exploit its `filepath.Ext()` processing to bypass script execution and obtain the raw source code of server-side scripts by appending NTFS-equivalent suffixes (such as `::$DATA`, trailing dot, or trailing space) to the URL, thereby leaking sensitive embedded secrets like database credentials, API keys, and `SetCookieSecret` values, which can lead to authentication bypass.

SimpleSAMLphp's Service Provider (SP) does not properly enforce the expected Identity Provider (IdP) for an SP-initiated login when a response from a different IdP is received, allowing an attacker to exploit CVE-2026-49284 in multi-IdP deployments to bypass authentication and authorization controls by substituting a lower-trust IdP's response for a higher-trust one, potentially gaining unauthorized access or elevating privileges if application authorization relies on the specific IdP used.

A critical vulnerability, CVE-2026-44179, exists in XWiki Pro Macros versions before 1.14.5, allowing remote code execution for any user with page editing rights due to improper escaping of page titles and content processed by the excerpt-include macro, leading to XWiki syntax injection and full compromise of the XWiki installation.

A critical pre-authentication reflected Cross-Site Scripting (XSS) vulnerability, tracked as CVE-2026-44203, in OpenIdentityPlatform OpenAM's `openam-oauth2` component allows an unauthenticated attacker to inject malicious scripts into a victim's browser context by manipulating the `state` parameter in OAuth2/OIDC `form_post` responses, leading to session hijacking or credential theft.

A critical pre-authentication remote code execution (RCE) vulnerability, CVE-2026-46495, exists in OpenDJ Community Edition affecting versions up to 5.1.0, where a deserialization of untrusted data issue in the JMX RMI connector allows unauthenticated attackers with TCP reachability to the JMX listener to execute arbitrary Java objects, potentially leading to full system compromise.

The `scim-patch` Node.js library, versions up to and including 0.9.0, is critically vulnerable to prototype pollution (CVE-2026-48170) when processing SCIM PATCH operations, allowing an attacker to modify `Object.prototype` process-wide through crafted `__proto__` keys in the request body, leading to potential privilege escalation or denial of service.

A critical vulnerability, CVE-2026-54352, in Budibase server allows an authenticated workspace builder to perform arbitrary file reads on the host system by uploading a crafted PWA zip file containing a symbolic link, leading to credential compromise and privilege escalation, potentially enabling a full global administrator takeover.

Gogs, a self-hosted Git service, is vulnerable to a Critical (CVSS 9.9) Remote Code Execution (RCE) via `git rebase --exec` argument injection (GHSA-qf6p-p7ww-cwr9) during pull request merge operations, allowing an authenticated attacker to execute arbitrary commands as the Gogs server process user and achieve full server compromise.

An attacker can chain multiple vulnerabilities in motionEye, including an arbitrary file read (LFI), a signature bypass using password hashes, and an unsafe configuration restore, to achieve unauthenticated remote code execution (RCE) if the normal user password is unset, or authenticated RCE from a normal user account.

An improper authorization vulnerability (CVE-2026-45052) in OpenAM Community Edition through version 16.0.6 allows an unauthenticated attacker to write persistent entries into the Liberty Discovery store on any user's LDAP entry and a shared root-realm Discovery branch, due to a flaw in the Liberty Web Services SOAP receiver that permits anonymous writes with elevated internal privileges, potentially influencing service routing or security mechanisms if Liberty discovery data is consumed.

A critical prototype pollution vulnerability (CVE-2026-48714) exists in `i18next-http-middleware` versions up to 3.9.6, where the `missingKeyHandler` fails to adequately sanitize dotted key segments, allowing attackers to manipulate `Object.prototype` when exposed to untrusted input and used with vulnerable `i18next-fs-backend` versions up to 2.6.5, potentially leading to configuration poisoning, security bypasses, crashes, or remote code execution.

Untrusted input can exploit a prototype pollution vulnerability (CVE-2026-48713) in `i18next-fs-backend` versions prior to 2.6.6, particularly via `i18next-http-middleware`'s `missingKeyHandler`, by submitting crafted missing-key strings that leverage the `keySeparator` to write arbitrary properties onto `Object.prototype`, leading to crashes, configuration poisoning, or security bypasses.

A low-privilege user with a freshly-provisioned SSO account in Netflix's Lemur certificate management service (versions <= 1.9.0) can exploit a Server-Side Request Forgery (SSRF) vulnerability in the ACME authority creation endpoint to reach the AWS EC2 Instance Metadata Service (IMDS), exfiltrating AWS STS credentials, and leveraging a creator-equality Insecure Direct Object Reference (IDOR) vulnerability for permanent access to PKI private keys, resulting in AWS IAM compromise and persistent certificate access.
