Improper Authentication

Overview Affected versions of this package are vulnerable to Improper Authentication when decoding JSON Web Tokens. An attacker can forge valid tokens by supplying a public key as the secret for the HMAC algorithm when both asymmetric and HMAC algorithms are supported. PoC python from jwt.apijws...

CVE-2026-48522

PyJWT is a JSON Web Token implementation in Python. Prior to 2.13.0, PyJWKClient passes its uri argument directly to urllib.request.urlopen which uses Python stdlib's default OpenerDirector registering HTTPHandler, HTTPSHandler, FTPHandler, FileHandler, and DataHandler. There is currently no...

CVE-2026-48522

PyJWKClient in PyJWT prior to 2.13.0 passes its uri argument directly to urllib.request.urlopen(), allowing attacker-controlled jku URLs to trigger SSRF and related token-forgery scenarios via file://, ftp://, or data: schemes. Affected component: PyJWKClient (Python). Root cause: lack of a schem...

pyjwt 代码问题漏洞

PyJWT is a Python library developed by José Padilla of the United States. It allows for the encoding and decoding of JSON Web Tokens JWTs. Prior to version 2.13.0, there were code vulnerabilities in PyJWT. These vulnerabilities stemmed from PyJWKClient directly passing the uri parameter to...

CVE-2026-44315

free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's NEF mounts the 3gpp-pfd-management API without inbound OAuth2/bearer-token authorization. A network attacker who can reach NEF on the SBI can create, read, and delete PFD-management transaction state with a...

HAXcms: Private Key Disclosure via Broken HMAC Implementation

Summary The hmacBase64 function in the HAXcms Node.js backend contains two critical cryptographic implementation errors that together allow any unauthenticated attacker to extract the system’s private signing key and forge arbitrary admin-level JSON Web Tokens JWTs allowing them to get full admin...

CVE-2026-31387 Apache OFBiz: Cookie Manipulation Allows Authenticated JWT Forgery and Account Impersonation

Improper Authentication vulnerability in Apache OFBiz. This issue affects Apache OFBiz: before 24.09.06. Users are recommended to upgrade to version 24.09.06, which fixes the issue...

CVE-2026-31387

CVE-2026-31387 concerns Apache OFBiz with an Improper Authentication issue affecting versions prior to 24.09.06. The CVE list entry emphasizes a cookie manipulation flaw that enables authenticated JWT forgery and account impersonation. The recommended remediation is upgrading to OFBiz 24.09.06. T...

Use Of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

Cloudreve is vulnerable to Use of Cryptographically Weak Pseudo-Random Number Generator PRNG. The vulnerability is due to the generation of security-sensitive secrets using math/rand seeded with predictable timestamps, which allows an attacker to recover the secret key, forge JWTs, and gain...

UBUNTU-CVE-2026-44699

LibJWT is a C JSON Web Token Library. From 3.0.0 to 3.3.2, libjwt accepts an RSA JWK that does not contain an alg parameter as the verification key for an HS256/HS384/HS512 token. In the OpenSSL backend, this causes HMAC verification to run with a zero-length key, so an attacker can forge a valid...

Inadequate Encryption Strength

Overview Affected versions of this package are vulnerable to Inadequate Encryption Strength due to insufficient enforcement of length and entropy requirements for the JWTSECRET configuration value. An attacker can gain unauthorized access to user accounts by forging authentication tokens using we...

CVE-2026-44523 Note Mark: JWT Secret Weakness allows Full Account Takeover via token forgery

Note Mark is an open-source note-taking application. Prior to 0.19.4, no minimum length or entropy is enforced on the JWTSECRET configuration value. The application accepts any base64-decodable secret regardless of size, including secrets as short as 1 byte. This vulnerability is fixed in 0.19.4...

CVE-2026-44523

CVE-2026-44523 affects Note Mark, with all versions before 0.19.4 vulnerable to a JWT secret weakness. The root cause is that the JWT secret is not validated for minimum length or entropy; the application accepts any base64-decodable secret, even as short as 1 byte. In backend/config/utils.go, Ba...

CVE-2026-44351

fast-jwt provides fast JSON Web Token JWT implementation. Prior to 6.2.4, a critical authentication-bypass vulnerability in fast-jwt's async key-resolver flow allows any unauthenticated attacker to forge arbitrary JWTs that are accepted as authentic. When the application's key resolver returns an...
