CVE-2026-1293195.9 MÉD—
——0create-ecdh is a browserifiable implementation of Node.js crypto.createECDH. In versions 4.0.4 and below, the JavaScript implementation (browser.js, used by browser bundlers and on Node.js versions without a working native crypto.createECDH) did not validate peer public keys in ECDH.prototype.computeSecret or ECDH.prototype.setPublicKey. The peer point was multiplied by the local private key without checking that it was on the configured curve or in its prime-order subgroup. An attacker who can submit public keys to a party that reuses a static private key can perform an invalid-curve or small-subgroup attack and recover the private key modulo small factors, eventually recovering the full key via the Chinese Remainder Theorem. For the ed25519 and curve25519 curves, low-order points were also accepted, which could force a predictable shared secret. On modern Node.js, create-ecdh re-exports the native implementation, which is not affected. This issue is fixed in version 4.0.5.1dCVE-2026-68510——
——0bit-vec is a compact vector of bits. Prior to version 0.10.0, there is undefined behavior if a user performs deserialize from an untrusted source and unsafe get_unchecked. A user of this library may be impacted by incorrect behavior if they perform deserialize from an untrusted source and run operations on the deserialized BitVec. This issue has been patched in version 0.10.0.2dCVE-2026-1191026.5 MÉD—
——0In Telerik UI for Blazor, versions v12.0.0 through 15.2.0, an improper input validation vulnerability exists, where the Grid, TreeList and Gantt's AI command filters on any model property, bypassing the declared column allowlist.2dCVE-2026-1075264.6 MÉD—
——0Dell PowerStore contains an improper input validation vulnerability. An authenticated low-privileged attacker could exploit this vulnerability, potentially leading to stored cross-site scripting in the management interface.2dCVE-2026-1262676.5 MÉD29.5%
——9NocoDB from 0.300.0 before 2026.04.4 contains a denial of service vulnerability that allows authenticated users to crash the server by triggering an unhandled promise rejection in MetaService metadata logging. Attackers can send a request leaving a lookup condition undefined, causing knex binding errors in the unawaited logHelper call that terminate the server process.1dCVE-2026-1263565.3 MÉD33.9%
——10Hono is a Web application framework that provides support for any JavaScript runtime. From 4.5.1 until 4.13.16, validator('form') uses a strict whole-header pattern that fails to recognize multipart/form-data when its Content-Type includes another legal parameter or extra whitespace after a semicolon. The validation callback receives an empty object even though c.req.parseBody() or c.req.formData() can still parse and expose all submitted fields to the handler. An unauthenticated client can therefore bypass allow-list or required-field checks when the application relies on the form validator and its callback accepts an empty object. application/x-www-form-urlencoded requests are not affected. This issue is fixed in version 4.13.16.2d
