Vision Ui

Vision UI is a collection of enterprise-grade, dependency-free modules for modern web projects. In versions 1.4.0 and below, the generateSecureId and getSecureRandomInt functions in security-kit versions prior to 3.5.0 (packaged in Vision UI 1.4.0 and below) are vulnerable to Denial of Service (DoS) attacks. The generateSecureId(length) function directly used the length parameter to size a Uint8Array buffer, allowing attackers to exhaust server memory through repeated requests for large IDs since the previous 1024 limit was insufficient. The getSecureRandomInt(min, max) function calculated buffer size based on the range between min and max, where large ranges caused excessive memory allocation and CPU-intensive rejection-sampling loops that could hang the thread. This issue is fixed in version 1.5.0.

Vision UI is a collection of enterprise-grade, dependency-free modules for modern web projects. In versions 1.4.0 and below, the getSecureRandomInt function in security-kit versions prior to 3.5.0 (packaged in Vision-ui <= 1.4.0) contains a critical cryptographic weakness. Due to a silent 32-bit integer overflow in its internal masking logic, the function fails to produce a uniform distribution of random numbers when the requested range between min and max is larger than 2³². The root cause is the use of a 32-bit bitwise left-shift operation (<<) to generate a bitmask for the rejection sampling algorithm. This causes the mask to be incorrect for any range requiring 32 or more bits of entropy. This issue is fixed in version 1.5.0.
