Summary
Bit flip attack vulnerability in cookie-encrypter
due to a weakness in the encryption method used in cookie-encrypter an attack can use the world visible IV to edit encrypted cookies without decrypting the cookie itself. This is known as an AES CBC bit flipping attack.
Impact
The application uses a cryptographic algorithm known to have weaknesses, such as MD5, SHA-1, or DES. Typical impact: compromised confidentiality or integrity of protected data.
CVE-2024-53441 has a CVSS score of 8.2 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. No fixed version is listed yet, so configuration controls and monitoring matter more in the interim.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2024-53441? CVE-2024-53441 is a high-severity use of a broken or risky cryptographic algorithm vulnerability in cookie-encrypter (npm), affecting versions <= 1.0.1. No fixed version is listed yet. The application uses a cryptographic algorithm known to have weaknesses, such as MD5, SHA-1, or DES.
- How severe is CVE-2024-53441? CVE-2024-53441 has a CVSS score of 8.2 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of cookie-encrypter are affected by CVE-2024-53441? cookie-encrypter (npm) versions <= 1.0.1 is affected.
- Is there a fix for CVE-2024-53441? No fixed version is listed for CVE-2024-53441 yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is CVE-2024-53441 exploitable, and should I be worried? Whether CVE-2024-53441 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2024-53441 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2024-53441? No fixed version is listed yet. In the interim: Replace the broken algorithm with a current recommendation: SHA-256 or higher for hashing, AES-GCM for symmetric encryption.
