The implementation of EdDSA in EdDSA-Java (aka ed25519-java) through 0.3.0 exhibits signature malleability and does not satisfy the SUF-CMA (Strong Existential Unforgeability under Chosen Message Attacks) property. This allows attackers to create new valid signatures different from previous signatures for a known message.

Matching of hosts against proxy patterns can improperly treat an IPv6 zone ID as a hostname component. For example, when the NO_PROXY environment variable is set to "*.example.com", a request to "[::1%25.example.com]:80` will incorrectly match and not be proxied.

## **Summary** A session hijacking vulnerability exists when an attacker-controlled **authoritative subdomain** under a parent domain (e.g., `subdomain.host.com`) sets cookies scoped to the parent domain (`.host.com`). This allows session token replacement for applications hosted on sibling subdomains (e.g., `community.host.com`) if session tokens aren't rotated post-authentication. **Key Constraints**: - Attacker must control **any subdomain** under the parent domain (e.g., `evil.host.com` or `x.y.host.com`). - Parent domain must **not** be on the [Public Suffix List](https://publicsuffix.org/). Due to non-existent session token rotation after authenticating we can theoretically reproduce the vulnerability by using browser dev tools, but due to the browser's security measures this does not seem to be exploitable as described. --- ## **Proof of Concept (Deno)** ```ts Deno.serve({ port: 8000, // default hostname: 'localhost', onListen: (o) => console.log(`Serve...

An issue in parse-git-config v.3.0.0 allows an attacker to obtain sensitive information via the expandKeys function.

### Summary An authentication bypass vulnerability was found in ruby-saml due to a parser differential. ReXML and Nokogiri parse XML differently, the parsers can generate entirely different document structures from the same XML input. That allows an attacker to be able to execute a Signature Wrapping attack. ### Impact This issue may lead to authentication bypass.

### Summary ruby-saml is susceptible to remote Denial of Service (DoS) with compressed SAML responses. Ruby-saml uses zlib to decompress SAML responses in case they're compressed. It is possible to bypass the message size check with a compressed assertion since the message size is checked before inflation and not after. ### Impact This issue may lead to remote Denial of Service (DoS).

### Summary There are 2 new Critical Signature Wrapping Vulnerabilities (CVE-2025-25292, CVE-2025-25291) and a potential DDOS Moderated Vulneratiblity (CVE-2025-25293) affecting ruby-saml, a dependency of omniauth-saml. The fix will be applied to ruby-saml and released 12 March 2025, under version 1.18.0. Please [upgrade](https://github.com/omniauth/omniauth-saml/blob/master/omniauth-saml.gemspec#L16) the ruby-saml requirement to v1.18.0. ### Impact Signature Wrapping Vulnerabilities allows an attacker to impersonate a user.

Name: ISA-2025-001: Non-deterministic JSON Unmarshalling of IBC Acknowledgement can result in a chain halt Component: IBC-Go Criticality: High (Considerable Impact; Likely Likelihood per [ACMv1.2](https://github.com/interchainio/security/blob/main/resources/CLASSIFICATION_MATRIX.md)) Affected versions: IBC-Go >= v7; Earlier IBC-Go versions MAY also be affected. Affected users: Validators, Full nodes, IBC Middleware authors ### Description An issue was discovered in IBC-Go's deserialization of acknowledgements that results in non-deterministic behavior which can halt a chain. Any user that can open an IBC channel can introduce this state to the chain. The following patch is in addition to the previous patch which now extends the same protection to all applications beyond transfer. ### Patches The new IBC-Go releases below address this issue: * [v7.10.0](https://github.com/cosmos/ibc-go/releases/tag/v7.10.0) * [v8.7.0](https://github.com/cosmos/ibc-go/releases/tag/v8.7.0) ### Worka...

Name: ISA-2025-002: x/group can halt when erroring in EndBlocker Component: CosmosSDK Criticality: High (Considerable Impact; Likely Likelihood per [ACMv1.2](https://github.com/interchainio/security/blob/main/resources/CLASSIFICATION_MATRIX.md)) Affected versions: <= v0.47.16, <= 0.50.12 Affected users: Validators, Full nodes, Users on chains that utilize the groups module Cosmos SDK chains in unpatched releases that use the `x/group` module are affected. ### Description An issue was discovered in the groups module where malicious proposals would result in an errors triggered in the module's end blocker that could result in a chain halt. Any set of users that can interact with the groups module could introduce this state. ### Patches _Has the problem been patched? What versions should users upgrade to?_ The new Cosmos SDK release [v0.50.13](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.50.13) and [v0.47.17](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.47.17) fix thi...
