CVE-2024-28864
Ilicmiljan Secureprops 1.2.0 … 1.2.1
Raw vector
CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:N/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2024-28864 is a low-severity Inefficient Regular Expression Complexity (CWE-1333) vulnerability in Ilicmiljan Secureprops. Its CVSS base score is 2.6 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked at the 25th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Vulnerability Data
SecureProps is a PHP library designed to simplify the encryption and decryption of property data in objects. A vulnerability in SecureProps version 1.2.0 and 1.2.1 involves a regex failing to detect tags during decryption of encrypted data. This occurs when…
more
the encrypted data has been encoded with `NullEncoder` and passed to `TagAwareCipher`, and contains special characters such as `\n`. As a result, the decryption process is skipped since the tags are not detected. This causes the encrypted data to be returned in plain format. The vulnerability affects users who implement `TagAwareCipher` with any base cipher that has `NullEncoder` (not default). The patch for the issue has been released. Users are advised to update to version 1.2.2. As a workaround, one may use the default `Base64Encoder` with the base cipher decorated with `TagAwareCipher` to prevent special characters in the encrypted string from interfering with regex tag detection logic. This workaround is safe but may involve double encoding since `TagAwareCipher` uses `NullEncoder` by default.
