The ':N' branch parses the number with `atoi(src)` and assigns it to the binder counter with no range check, so a statement containing ':2147483648' leaves the counter negative (-2147483648 with glibc, where atoi wraps). Each following '?' then expands through `sprintf(start, \":p%d\", idx++)` to ':p-2147483648', 14 bytes with the terminating NUL where the buffer budgets 7. The placeholder limit added in 1.650 tests the counter against 99,999, which a negative counter passes.\n\nAny caller that preparses an untrusted statement into ':pN' style placeholders gets a heap out-of-bounds write that grows with the number of '?' marks following the poisoned placeholder. The '?' and '%s' return styles compare the parsed number against the expected sequence and error out, and are unaffected." } ], "problemTypes": [ { "descriptions": [ { "cweId": "CWE-1284", "description": "CWE-1284 Improper Validation of Specified Quantity in Input", "lang": "en", "type": "CWE" } ] }, { "descriptions": [ { "cweId": "CWE-787", "description": "CWE-787 Out-of-bounds Write", "lang": "en", "type": "CWE" } ] } ], "providerMetadata": { "orgId": "9b29abf9-4ab0-4765-b253-1875cd9b441e", "shortName": "CPANSec", "dateUpdated": "2026-08-15T12:09:22.962Z" }, "references": [ { "tags": [ "vendor-advisory" ], "url": "https://github.com/perl5-dbi/dbi/security/advisories/GHSA-623j-hfpc-mrc4" }, { "tags": [ "patch" ], "url": "https://github.com/perl5-dbi/dbi/commit/29b72ae7d2a8114a734a55840bf1c45b89207809.patch" }, { "tags": [ "related" ], "url": "https://www.cve.org/CVERecord?id=CVE-2026-14739" }, { "tags": [ "related" ], "url": "https://www.cve.org/CVERecord?id=CVE-2026-10879" } ], "solutions": [ { "lang": "en", "value": "Upgrade to DBI 1.652 or later." } ], "source": { "discovery": "UNKNOWN" }, "title": "DBI versions before 1.652 for Perl allow a heap out-of-bounds write via an unvalidated numeric placeholder that sets the binder counter in preparse", "workarounds": [ { "lang": "en", "value": "For deployments that cannot be upgraded, limit SQL statements to 99,999 placeholders." } ], "x_generator": { "engine": "cpansec-cna-tool 0.1" } }, "adp": [ { "metrics": [ { "cvssV3_1": { "scope": "UNCHANGED", "version": "3.1", "baseScore": 9.1, "attackVector": "NETWORK", "baseSeverity": "CRITICAL", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "NONE", "confidentialityImpact": "HIGH" } }, { "other": { "type": "ssvc", "content": { "timestamp": "2026-08-17T20:29:15.870047Z", "id": "CVE-2026-73194", "options": [ { "Exploitation": "none" }, { "Automatable": "yes" }, { "Technical Impact": "partial" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-08-17T20:29:56.764Z" } } ] } }
