### Impact When parsing compact JWS or JWE input, go-jose could use excessive memory. The code used strings.Split(token, ".") to split JWT tokens, which is vulnerable to excessive memory consumption when processing maliciously crafted tokens with a large number of '.' characters. An attacker could exploit this by sending numerous malformed tokens, leading to memory exhaustion and a Denial of Service. ### Patches Version 4.0.5 fixes this issue ### Workarounds Applications could pre-validate payloads passed to go-jose do not contain an excessive number of '.' characters. ### References This is the same sort of issue as in the golang.org/x/oauth2/jws package as CVE-2025-22868 and Go issue https://go.dev/issue/71490.

### Summary A bypass was found for the security feature **trustedOrigins**. This works for wild card or absolute URLs trustedOrigins configs and opens the victims website to a **Open Redirect** vulnerability, where it can be used to steal the **reset password token** of a victims account by changing the "callbackURL" parameter value to a website owned by the attacker. ### Details #### Absolute URLs The issue here appears in the **middleware**, [specifically](https://github.com/better-auth/better-auth/blob/ddebd0358d74376ea64541512d0167dd4377f182/packages/better-auth/src/api/middlewares/origin-check.ts#L53). This protection is not sufficiente and it allows attackers to get a open redirect, by using the payload `/\/example.com`. We can check this is a valid URL ( or it will be a valid URL because the URL parser fix it for us ), by checking the image bellow:  ```typescript // trustedOrigins = [ ...

A botnet of 130,000 devices is launching a Password-Spraying attack on Microsoft 365, bypassing MFA and exploiting legacy authentication to access accounts.

The http parser in Phusion Passenger 6.0.21 through 6.0.25 before 6.0.26 allows a denial of service during parsing of a request with an invalid HTTP method.

### Summary The application is vulnerable to an open redirect due to improper validation of the callbackURL parameter in the email verification endpoint and any other endpoint that accepts callback url. While the server blocks fully qualified URLs (e.g., https://evil.com), it incorrectly allows scheme-less URLs (e.g., //malicious-site.com). This results in the browser interpreting the URL as https://malicious-site.com, leading to unintended redirection. bypass for : https://github.com/better-auth/better-auth/security/advisories/GHSA-8jhw-6pjj-8723 ### Affected Versions All versions prior to 1.1.19 ### Details The application’s email verification endpoint (/auth/verify-email) accepts a callbackURL parameter intended to redirect users after successful email verification. While the server correctly blocks fully qualified external URLs (e.g., https://evil.com), it improperly allows scheme-less URLs (e.g., //malicious-site.com). This issue occurs because browsers interpret //malicious-si...

OpenH264 recently reported a [heap overflow](https://github.com/cisco/openh264/security/advisories/GHSA-m99q-5j7x-7m9x) that was fixed in upstream [63db555](https://github.com/cisco/openh264/commit/63db555e30986e3a5f07871368dc90ae78c27449) and [integrated into](https://github.com/ralfbiedert/openh264-rs/commit/3a822fff0b4c9a984622ca2b179fe8898ac54b14) our 0.6.6 release. For users relying on Cisco's pre-compiled DLL, we also published 0.8.0, which is compatible with their latest fixed DLL version 2.6.0. In other words: - if you rely on our `source` feature only, >=0.6.6 should be safe, - if you rely on `libloading`, you must upgrade to 0.8.0 _and_ use their latest DLL >=2.6.0. Users handling untrusted video files should update immediately.
