Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable system is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or through terminal emulation (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., using social engineering techniques to trick a legitimate user into opening a malicious document).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Definitions: FIRST CVSS v4.0 specification.

Exploitation evidence

Disclosed: evidence found.
CVE published 12 Mar 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: evidence found.
CVSS exploit maturity: proof of concept public
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 29 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade jarikomppa/soloud to 20200207.

AI-suggested

To mitigate CVE-2026-4009, organizations should upgrade the soloud library to version 20200207 or later, where the vulnerability has been addressed. Additionally, implement strict local access controls to limit untrusted users from executing or introducing malicious audio files that could trigger the vulnerability. Employ application whitelisting and file integrity monitoring to detect unauthorized modifications or suspicious files. For environments where upgrading immediately is not feasible, consider sandboxing or isolating applications that process untrusted audio files to contain potential crashes or data leaks. Finally, conduct security testing on audio processing components to identify similar vulnerabilities proactively.

Description

A vulnerability has been found in jarikomppa soloud up to 20200207. Impacted is the function drwav_read_pcm_frames_s16__msadpcm in the library src/audiosource/wav/dr_wav.h of the component WAV File Parser. The manipulation leads to out-of-bounds read. The attack needs to be performed locally. The exploit has been disclosed to the public and may be used. Upgrading to version 20200207 is recommended to address this issue. It is recommended to upgrade the affected component. The project was informed of the problem early through an issue report but has not responded yet.

Impact

The primary impact of CVE-2026-4009 is the potential for local attackers to cause out-of-bounds reads in applications using the vulnerable soloud library for audio processing. This can lead to application crashes, resulting in denial of service or instability in software relying on this library. Additionally, out-of-bounds reads may expose sensitive memory contents, potentially leaking information that could be leveraged in further attacks. Since exploitation requires local access and limited privileges, remote exploitation is not feasible, reducing the overall risk. However, in environments where untrusted users have local access or where malicious files can be introduced locally (e.g., multi-user systems, shared workstations, or developer environments), the vulnerability could be leveraged to disrupt operations or gather sensitive data. Organizations embedding this library in multimedia applications, games, or audio processing tools should be aware of the risk to maintain application stability and data confidentiality.
