Alleged

IntCyberDigest reports that seven of 45 security findings submitted by Mythos have so far been accepted as curl vulnerabilities, all rated low severity. The remaining findings were described as 37 ordinary bugs and one false report.

What happened

Alleged

According to IntCyberDigest, Mythos flagged 45 potential security issues in curl. The outlet attributes the assessment of the set to curl lead developer Daniel Stenberg: seven vulnerabilities, 37 findings that are "just a bug," and one considered completely false.

Why it matters

Alleged

The reported review sharply narrows the security picture from 45 flagged findings to seven accepted vulnerabilities, while still leaving a small set of issues that users and maintainers may need to evaluate. IntCyberDigest also describes curl as being present in billions of devices, but the supplied evidence does not independently substantiate that reach.

What to do

Observed

The supplied posts do not name affected curl versions, CVE identifiers, patches, mitigations, or upgrade instructions. They therefore do not support a specific remediation step beyond waiting for technical advisories or release information.

Confirmed and still uncertain

Observed

The reported tally is clear: seven findings are described as confirmed, low-severity vulnerabilities, 37 as bugs, and one as false. Unknown from this evidence are the underlying flaws, affected components and versions, exploit conditions, disclosure timeline, and whether fixes are already available.

What people are saying

Alleged

IntCyberDigest says Stenberg characterized 37 findings as "just a bug" and one as completely false. A follow-up post attributes another point to him: curl is gradually raising the threshold for what it accepts as a low-severity vulnerability.

Evolution

Alleged

The evidence presents the review as ongoing, using the phrase "so far" for the seven confirmed vulnerabilities. It also reports a broader policy shift in which curl is becoming more selective about classifying low-impact defects as security vulnerabilities.

Reach

Observed

4 independent groups, 1 updates, and 5 engagements.

Technical detail

Alleged

The reported classification accounts for all 45 findings: seven vulnerabilities, 37 non-security bugs, and one false finding. All seven accepted vulnerabilities are described as low severity, but no weakness types, attack paths, severity scores, or reproduction details are provided.

Sources and evidence

Observed

The substantive evidence consists of two IntCyberDigest posts, one giving the 45-finding breakdown and another describing curl's changing threshold for low-severity reports. The supplied material does not include the underlying Mythos report, a curl advisory, or a direct statement with technical details, so the central claims remain secondhand.
