Summary

CVE-2026-8636 is a medium-severity Cleartext Storage of Sensitive Information in Memory (CWE-316) vulnerability in Ibm Datacap. Its CVSS base score is 5.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Credential Dumping (T1003); ranked at the 4th 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 SC-39 (Process Isolation) and SI-16 (Memory Protection) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SI-16 Memory Protection good match
prevent

Directly implements memory protection safeguards to prevent unauthorized disclosure of sensitive data such as passwords and cryptographic keys stored in cleartext.

SC-39 Process Isolation good match
prevent

Enforces process isolation so that an attacker cannot access memory belonging to other processes containing passwords or keys.

AC-3 Access Enforcement partial match
prevent

Enforces access control decisions that restrict which subjects can read or retrieve sensitive credential material from memory.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.DS-10 mostly match
prevents

Explicitly calls for removing confidential data from process memory, directly mitigating cleartext storage.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
detects

Security testing can detect cleartext secrets in memory dumps or debug output.

A.8.10 Information deletion partial match
degrades

Secure deletion practices reduce residual cleartext after use, but do not prevent initial storage.

A.8.12 Data leakage prevention partial match
mitigates

DLP tooling can monitor and block processes that leave sensitive data unencrypted in memory.

A.8.24 Use of cryptography partial match
prevents

Cryptographic controls can mandate encryption of sensitive data in memory, directly reducing cleartext exposure.

A.8.25 Secure development life cycle partial match
prevents

Secure-SDLC processes include memory-handling reviews that catch this weakness.

A.8.28 Secure coding partial match
prevents

Secure-coding standards explicitly require avoiding plaintext storage of secrets in RAM.
