Multi-Task Learning in CodeT5 Pretraining Enhances Cross-Language Vulnerability Detection
Abstract
Abstract: This report synthesises findings from 16 peer-reviewed papers addressing the following research question: What is the impact of multi-task learning during CodeT5 pretraining on its ability to generalize across programming languages in vulnerability detection tasks, as measured by F1 scores on the CWE-200. 11 claims were extracted from source literature; 0 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 3.5/10. This report is a machine-generated literature synthesis and does not constitute original research.
Research Question
What is the impact of multi-task learning during CodeT5 pretraining on its ability to generalize across programming languages in vulnerability detection tasks, as measured by F1 scores on the CWE-200 dataset?
Verification Level
| Paper level | L2, Source-grounded claims | |
| Source-grounded claims | 11 | |
| Claim record source | parsed source sections |
Descriptive public verification status only; aggregate claim counts are public, but individual claim records are not exposed here.
Quality Tier
| Tier | Quarantine candidate | |
| Basis | Review score is below 5.0; source-level inspection is required before relying on the synthesis. |
Descriptive public triage only; this tier does not alter current publication or DOI behavior.
Quality Dimensions
| Evidence strength | LOW | |
| Citation grounding | MEDIUM | |
| Uncertainty disclosure | MEDIUM | |
| Reproducibility status | MEDIUM |
Automated triage signals derived from public fields; not human peer review or independent validation.
Correction Record
| Status | CURRENT |
| Correction count | 0 |
