CVE-2026-76998 (HIGH) — details, PoC & remediation

Official description

NVD · unedited

A security vulnerability has been detected in SourceCodester Simple Online Food Ordering System 1.0. The impacted element is an unknown function of the file /admin/ajax.php?action=delete_category. Such manipulation of the argument ID leads to sql injection. It is possible to launch the attack remotely. The exploit has been disclosed publicly and may be used.

Technical summary

dbcve analysis

How this class of weakness works · CWE-74

Untrusted input crosses into a downstream interpreter — SQL, a shell, an HTML page, an LDAP query — without being kept separate from the commands around it, so the attacker's data is read as instructions. This is the parent class behind SQL injection, cross-site scripting, and command injection alike. The durable fix is the same everywhere: keep data and code apart at every boundary, using parameterisation or context-aware encoding rather than building interpreted strings by concatenation.

Remediation

From vendor data

No vendor fix exists The vendor has not published a patch for this.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.

Add your voice

Free. We build fixes in the order the community asks for them — and we’ll tell you the moment this one lands.

Can’t wait

We develop and verify an original fix where the vendor hasn’t, from $4,900. Deployed to your staging first — never straight to production.

The CVSS 7.3 rating on this SQL injection in SourceCodester's Food Ordering System misses the real threat picture because it treats authentication as the primary guardrail — and that guardrail is far weaker than typical CVE analysis assumes. The vulnerability lives in an admin/ajax.php endpoint and requires authentication, but SourceCodester deployments overwhelmingly ship with default credentials (admin/admin) that operators rarely change. For this platform, 'authenticated' translates to 'accessible to anyone running credential stuffing or simply trying defaults.' The EPSS score of 0.00263 measures automated scanning for this specific CVE, which is low right now — but historical SourceCodester CVEs show a predictable 2-4 week lag between disclosure and Shodan indexing, followed by exploitation spikes. The public exploit disclosure removes the technical barrier entirely. What makes this CVE particularly dangerous is the genealogical pattern: vendor patches are consistently narrow, fixing only the reported endpoint while leaving structurally identical queries in adjacent functions (delete_order, delete_menu, delete_user) unpatched. Each CVE disclosure effectively maps the remaining attack surface. These systems also sit at significant data gravity — payment information, customer addresses, delivery logistics — meaning admin panel compromise enables horizontal movement that CVSS cannot model. Prioritize these actions: First, audit any SourceCodester Food Ordering deployment in your environment immediately for default or weak admin credentials and force a change. Second, assume the entire admin namespace contains equivalent SQL injection — audit all delete, update, and insert operations in admin/ajax.php and adjacent files, not just the reported endpoint. Third, treat this as an abandoned codebase with no security update cadence; plan for manual remediation or retirement rather than waiting for a comprehensive patch. Fourth, monitor Shodan and attack surface tools for your organization's IP ranges — if these systems are exposed to the internet, treat them as already compromised until proven otherwise. The deployment population that never changed 'admin/admin' is also the population that will never patch — your defensive strategy must account for that gap.

Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.
