CVE-2026-124023Apache Axis2/C out-of-bounds read
CVE-2026-124023 is a out-of-bounds read in Apache Axis2/C, not yet scored.
Why this priority: Not scored yet, and no exploitation signal.
Published · Updated · NVD status: Received
What it is
Code reads past the end of a buffer, leaking memory contents or crashing.
How it is reached
The record does not say yet how the flaw is reached; the description below is the best guide until it is scored.
What an attacker gains
Its impact has not been scored yet. In practice, this kind of flaw lets an attacker crash the process, read memory, or in the worst case run code.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- No fixed version is listed yet. Find every place Apache Axis2/C runs, watch the references for a fix, and plan a replacement if it is no longer supported.
Description from NVD
Out-of-bounds Read vulnerability in the Guththila XML parser wrapper of Apache Axis2/C. On some malformed XML input the Guththila parser returned a raw input byte in place of an event code, and the AXIOM reader wrapper used that value as an index into a ten-entry lookup table without checking its range, reading heap memory past the end of the table. An unauthenticated client could trigger this by sending a crafted XML request to a server built with Guththila, the default parser, causing the request to be parsed incorrectly or, in some cases, the process to crash. The memory read is not returned to the client. This issue affects Apache Axis2/C: through 2.0.0. The fix is available in commits 23110287924e79d05a5b4712298c355d1f05c606 and f01683ec10e8fddb87279ec9351b3239021223e6 and will be included in the next release.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Native code: operating systems, browsers and firmware. The flaw sits wherever native code reads untrusted data.
- Network appliances and media or file parsers. The flaw sits wherever native code reads untrusted data.
Trust boundaries in play
- Wherever native code reads untrusted data. An attacker who crosses it can crash the process, read memory, or in the worst case run code.
Questions to answer about your own systems
- Where does Apache Axis2/C run in your systems, and at which version?
- Which of those instances are reachable by people you do not trust?
- What can it reach once compromised: which data stores, secrets and services?
